Description

CHARGE—BEAEMNG CYCLGDEXTRlN PGL‘thERlC h/lATERlALS AND h/lli'l‘lrlGDS 0F hlAKlNG AND USlNG SAhllij mmnmunmm {twill} Organic niicropollutants (MPs) are present in water resources at ng L"1 to pg L—1 concentrations as a uence of human activitiesl’2 Concerns about their negative effects on human health3"7 and the environmentg‘m motivate the development of technologies that remove lvll?’s more effectively."16 MPs span a wide variety of cheniical properties including surface charge, size, and chemical functionality. Charged Ml’s can he cationic, c, or zwitterionic and are typically difficult to remove in the ce of complex matrix constituents like natural organic matter (NOM) using conventional adsorption methods like activated carbon.

Of the anionic h/lPs, PFASs present a particular nmental prohleni because of their resistance to hiodegradation and correlation to negative health s. PFASs have been used in the formulations of thousands of consumer goodsl and are present in aqueous foam formulations used to ss on fires in training scenarios. ""9 As a result, they have contaminated surface and ground waters near thousands of airports and, military installations.20 ln 2016, Hu and coworkers showed that at least 6 million Americans were served drinking water contaminated with PFASS at or above the US EPAs 20l6 health advisory limit for pertluorooctanoic acid (PFOA) and pertluorooctanesulfonic acid (PFOS) of 70 ng liil.21 PFASs have been linked to cancers,3 liver damage,4 thyroid disease5 and other health problems.6 {lllll‘tZ} Contaminated water systems are typically iated with granular activated carbon (GAG), but its modest affinity for PFASS, particularly short chain tives, makes it an ive and stop~gap solution."24 in recent reports, 14’13 it was discovered that noncovalent interactions and the electrostatics of functional groups influence PFAS affinity to adsorbents, For example, a combination of fluorophilic interactions of the crosslinlter and a lower concentration of anionic charged functional groups in uorohiphenyldinlred CDPs led to high PFOA and PFOS removal from water. in contrast, CDPs crosslinked by epichlorohydrin exhibited inferior FFAS removal.25 {(3893} Adsorption processes can be employed to remove specific inants or contaminant classes from fl uids like air and water. Activated carbons (A (Is) are the most widespread sorhents used to remove organic ants, and their efficacy derives ily from their high surface areas, nanostructured pores, and hydrophobicity. However, no single type ofAC removes all contaminants well, particularly anionic h/ll’s. Because of their poorly defined structure and binding site ion, optimal adsorption selectivities e empirical screening at new installations, precluding rational design and, improvement. Furthermore, regenerating spent AC is energy intensive (heating to Siltlngt‘it‘i" C or other energy intensive procedures) and does not restore full performance. AC also has a slow pollutant uptake rate, achieving its uptake equilibrium in hours to days, such that more rapid contaminant removal requires excess sorbent.

Finally, AC can m poorly for many ng contaminants, particularly those that are relatively hydrophilic.

{Wild} An alternative adsorbent material can he made from polymeric cyclodextrin materials ed from insoluble polymers of B—cyclodextrin (B—CD), which are toroidal macrocyeles comprised of seven glucose units whose internal cavities are capable of binding organic compounds. Ei—CD is an inexpensive and sustainably produced monomer derived from cornstarch that is used extensively to formulate and stabilize pharmaceuticals, flavorants, and fragrances, as well as within chiral chromatography stationary phases. lnsoluhle ?—CD polymers have been formed by crosslinlsing with epichlorohydrin and other reactive compounds, and feature well d binding sites and high association constants, hle Ei—CD polymers crosslirtked with epichlorohydrin have been investigated as alternatives to AC for water purification, hut their low surface areas result in interior sorhent mance relative to ACs. {(3895} Thus there is a need for new sorbents that address the deficiencies ofAC and the like and which will e more effective sorption and/or sequestration properties for MPs (such as anionic MPs). Th ere is a need for an adsorbent that provides rapid anionic MP extraction, high total uptake, and facile regeneration and reuse procedures.

For example, in some embodiments, the composition comprises porous polymeric materials comprising a plurality of cyclodestrins crosslinlred with a plurality of crosslinlrs comprising formulatl), and/or (ll), and/or (ill).

Examples of support materials include cellulose (eg, cellulose ), carbon—based materials such as activated carbon, ne oxide, and oxidized carbon materials, silica, alumina, natural or synthetic polymers, and natural or synthetic polymers modified to include surface hydroxyl groups. One of shill in the art will recognize that any material with ical or other properties suitable to act as a t, which can covalently bond to the porous polymeric material, or can serve as a suitable support material if the porous polymeric material is adhesively bonded to the support via a suitable binder material. In an embodiment, the composition is in the form a membrane or a column g material. In an embodiment, the support is a fiber (eg a cellulose, nylon, polyolet‘in or polyester . to an ment, the support is a porous particulate material (eg, porous silica and porous alumina} In an embodiment, the support is a woven or non~woven fabric. In an embodiment, the support is a garment (such as a protective garment) or a surgical or medical drape, dressing, or sanitary article. {(3981} in some embodiments, the P~CDP may be grafted or bonded (eg chemically or mechanically bonded) onto a support to provide an adsorbent where the particle size and morphology are ontrolled to give ideal flow characteristics The term "mechanical bonc " refers to a bond formed between two materials by pressure, ultrasonic attachment, and/or other mechanical bonding process without the ional application of heat, such as mechanical entanglement. The al entanglement and wrapping of mi crofibrils to hold in place micron— sized particulate matter is a prime example of a mechanical bond. The term mechanical bond does not comprise a bond formed using an adhesive or chemical grafting. ln some ments, the PuCDl’ may be grafted or bonded {eg or ically bonded) onto a support to / 5 chemically provide an adsorbent where the particle size and morphology are r engineered (e.g by ation or milling) to provide particles with a wellucontrolled size and morphology to give ideal flow characteristics. {8882} The support complex may be prepared by a variety of methods, including conventional grafting methods. As used herein, the term "grafting" refers to covalently attaching lLCDl’s to a substrate surface through coupling ons between one or more functional groups on the ECU? and one or more functional groups on the substrate. in some embodiments, ng includes an "in situ" process as described herein in which cyclodextrins, linking groups of the present disclosure, and a substrate having surface bound nucleophiles (eg, hy dross/ls) are reacted together such that the linking groups of the present disclosure reacts with the hydroxyl groups of the cyclodextrins and the surface nucleophiles of the substrate, forming a P—CDP which is partially bonded via one or more linking groups of the present disclosure to the substrate. The substrate having surface hound nucleophiles include, but are not limited to hydroxyls (such as niicrocrystalline cellulose), amines, phosphines, and thiols. {9983} In some embodiments, "grafted" P—CDl’~support complexes are prepared by first synthesizing the l’~CDPs in a dedicated al r with te control of the reaction conditions and material purification to e optimized P-CDP particles. The PnCDPs are then chemically d with a suitably functionalized substrate. For example, a substrate functionalized with carboxylic acid groups (or activated fornis thereof such as acid halides, anliydrides, etc. known in the art) can react with one of more hydroxyls on the P—CD‘P to form an ester bond with the substrate. Alternatively, the P~CDP can be appropriately functionalized (eg, by selection of a functionalized cyclodextrin as described herein) of by a subsequent modification of the P—CDP such that it can react with suitable functional groups on the substrate.

Any suitable reaction chemistries can be plated, such as reactions between carboxylic acids (and derivatives thereof) and hydroxyls to form ester bonds, reactions between carboxylic acids (and derivatives th ereof) and amine groups to form amide bonds, reactions between isocyanates and alcohols to make urethanes, reactions between isocyanates and amines to make ureas, reactions n cyclic carbonates and amines to make urethanes, reactions between thiols and alhenes or alkynes to make ethers, reactions between epoxides and amine , photochemical reactions between acrylates, niethacrylates, thiols etc, and olefins, and so forth.

The reactive functional groups described herein can be on either of the 9—510? or substrate provided the reaction forms a covalent bond between the ate and the PACE? For example, of the ve functional groups are yls and carboxylic acids (forming an ester bond after reaction), the hydroxyl groups can be present on the PuCDP and the carbonyl groups on the ate or viceuversa. {8884} in other embodiments, the substrate can be coated with a "primer" having reactive functional groups as described above. The primer adheres to the surface of the substrate, and under suitable conditions can react with a suitably functionalized P433? to for a covalent bond between the P—CDP and the primer. {8885} The P—CDP particles may be engineered to achieve ic particle sizes. in some embodiments, the P—CDP is produced in the form of crosslinlred les which may require further reduction in size leg, for the es of forming stable sions or slurries, or in providing optimal flow characteristics). A variety of means that are readily apparent to a skilled artisan can be employed to reduce the le size of the l’nCDP such as ng or milling.

Grinding and milling can be employed to create smaller particles with sizes less than l micron.

Typical milling operations can be used by a skilled artisan and include both wet and dry milling.

Milling can be employed through a variety of s including, but not d to: ball mill, autogeneous mill, SAG mill, pebble mill, rod mill, Buhrstone mill, tower mill, vertical shaft impactor mill, and the like. Milling media includes, but is not limited to: metals, silicates, and other inorganic materials in various form factors including, rods, balls, and irregular shapes. In some embodiments, the milling is performed on dry RC1")? powder al in a dry process to produce a finer dry powder or on wet aqueous slurries of the P—CDP powder with or without emulsifying agents to produce a finer particulate dispersion. Eniulsifying agents may be used and are readily apparent to a skilled artisan, including, but not limited to: small molecule and polymeric surfactant compounds with nonionic, anionic, or ic character. A skilled n will appreciate that using fine particulate form factors will enable a variety ofbenefits, such as ( l) more stable aqueous dispersions that remain homogeneous over time by ing separation, (2) enable a high g of material by weight in the dispersion with values of 50% by weight or higher, (3) produce particulate matter that can be evenly coated or applied to various substrates, surfaces, fibers, yarns, fabrics and the like to produce a finished material with minimal perceptible changes in "hand," and (4) produce sions that are stable to dilution and blending with other emulsions or solutions such as binders, surfactants, g agents, or softeners. in some embodiments, the final particle diameter includes l0 micron, l0~l 5 micron, and lS—ZO micron, or ranges therehetween. {8886} lf larger particle sizes are desired, the composition may be granulated to form agglomerates of larger particle size. Thus, in some ments, granules (eg, self~supporting es) are produced from PuCDP particle powders of various sizes. Broadly, this process will transform P—CDP particle powders in the size regimes ranging from lu30 microns to granules in excess or" lot} microns, 200 microns, 300 microns, and larger. This process may be ed via granulation techniques common to the pharmaceutical industry {1721;152:500}; omenai’crrion Technology, Ed. Parilrh, D. 1%, 2005, Taylor & Francis Group) in which the powders are bound together via physical and/or chemical means in batch or continuous modes. ln the simplest form, particles of the P—CDP are blended mechanically with a fluid (cox, aqueous) mixture containing an adhesive hinder — typically a synthetic, ynthetic, or l polymer. Suitable semi" synthetic polymers that can be used include cellulose etheis, specifically ethylcellulose, methylcellulose. ypropylcellulose, carboxymethylcellulose, starch and starch derivatives, and . Suitable fully synthetic polymers such as polyvinylpyrrolidone or polyethylene glycol can be used. Other suitable hinders e sizes and other coatings used in the textile industry and paper industries including ide amine epichlorohydrin (FAB) or polymeric glyoxal crosslinlcers, polyvinylalcoliol, and starch~hased sizes. ln order to create robust granules which are resistant to dissolution in water or other solvents, r covalent crosslinking may he facilitated via the addition of small molecule crosslinhers such as l, formaldehyde, yanate, and/or diepoxide functionalities. in addition to nt crosslinlring electrostatic agglomeration of polyelectrolytes can also be utilized as a binding motif in which cationic polyelectrolytes form suitable adl'iesiye properties when blended with anionic polyelectrolytes in the presence of P-CDP powders and/or t structures. Polyca‘tions can comprise those commonly used for flocculation including, but not limited to polydiallyldimethylarnmonium chloride (polyDADh/lAC), acidic polyethyleneimine, and polyacrylamides. Polyanions can comprise those commonly used for flocculation including, but not limited to sodium polyacrylate, sodium polystyrene sulfonate, and polyvinylsulfonate. {(3887} ical blending during the granulation may he achieved via low shear processes such as rotary drum mixing or overhead mechanical stirring. As will be readily apparent to a slrilled artisan, the stirring rate and total length of stirring time effects the granule size.

Granulation may also he conducted in fluidized beds or via spray drying techniques. ln each case, the ECU? particle are combined with the aqueous or solvent borne mixture containing the binder compounds and the ical or physical agitation is conducted at a specified shear for a determined number of cycles. The ant particles will display a step growth change in their average diameters and can also display a changed polydispersity. The physical properties of these granules depend on the binder selected, the crosslinlring chemistry, and the al process used in their granulation. These larger granular particles will be suitable for packed bed column filtration commonly employed for water filtration and industrial separations. {8888} ln some embodiments, the present disclosure provides a stable aqueous dispersion comprising P—CDP particles. ln some embodiments, the 1’—CDP particles of the present disclosure, which can be used in such stable aqueous dispersions are from about l pm to about 150 urn.

In some embodiments, the P—CDP particles are mechanically entangled in continuous filament yarn. As will be readily apparent to a skilled artisan, a special subset of yarn finishing enables the mechanical binding of ulate matter within a continuous filanient yarn in some circumstances. When a yarn leg, uous filament) comprised of multiple filaments of a l tic polymer such as polyethyleneterephthalate (PET) or polyamide (nylon 6 or nylon 6,6) that bears n'iicrofibrilla‘ting tendencies on each nt surface, there exists the possibility to incorporate particulate within the yarn s. The P— CDP particles of the present sure can be incorporated into the yarn in a variety of ways One non—limiting example is to apply a dispersion of the P—CDP les of interest via dip coating or oil roll application onto a moving yarn bundle during the false twist texturing process. ln this process, the filaments are mechanically separated via twisting, first in one direction followed by the opposite direction. After the first ng, the filaments are individualized and void space is presented within the yarn bundle. The dispersion solution is applied at this point within the process after which the bundles are twisted back to the standard orientation and the yarn heated to dry the solution. This process enables the application of dispersion particles within the yarn bundles that are held in place by the continuous filaments and microfibrils emanating from the continuous filament surface. Such approaches have been used to apply various micron sized particles to continuous filament yarns, including microcapsules (US Patent Publication No. EGGS/0262646 Al which is hereby incorporated by reference in its entirety), metallic silver inieroparticles (US Patent Publication No. 36l595 Al which is hereby incorporated by reference in its ty), and (US Patent Publication No. 2006/0067965 Al, which is hereby incorporated, by reference in its entirety) other functional particles to synthetic fiber yarn bundles. These ed and particle loaded yarns may then be processed through typical means to create knit and woven fabrics for use in apparel, upholstery, medical, displays, or other uses. {99125; In some embodiments, the PSI)? particles are incorporated, into thermally—bonded, particulate pressed forms.

Such form factors can contain as high as 95% by weight lb CDP particles, with the addition of fibrillating fibers (Fybrel?l), 'l'encel"M, or Cll‘FTM), sometimes inorganic materials such as attapulgite clays, and finally an organic binder material (most typically ose esters and similar tives) to create a porous ite structure with adequate mechanical strength and particulate holding efficiency for medium pressure filtration ations such as faucet filters and refrigerator filters (US Patent Nos 5,488,02l and 8,l6’7, l 4i both of which are hereby incorporated by reference in their ties). {£39126} P—CDP dry les or dispersion can be used in place of or blended with other adsorbent materials to form such a composite adsorbent P—CDP particulate—containing forms as described above In such embodiments, the solid dry ents may be dry blended, optionally including dry P-CDP particles and organic binder powder with or without inorganic clays and/or fibrillating , If an aqueous dispersion of P—CDP les is used, they may be diluted with water and added to the mixture. Water is added (egg in 80~l 50 wt%) and the mixture is blended (eg under high shear) to create a plastic material. This n'iaterial may be formed into the desired form factor, dried and cured at temperatures ranging from l25 to 250 "C.

This final form factor presents the PCB? adsorbent particles in a form factor common to and useful for point of use water filters, {99127} in some embodiments, the P~CDP particles are oration into solution sed polyiner form factors. A, variety of means are available to produce filter membrane materials.

For example, via solution cast films or extrude hollow fibers of membrane polymers where controlled coagulation creates a sed film of controlled pore size. ln some embodiments, a polymer such as ose acetate dissolved in a water miscible organic solvent such as NMP, DMSQ, or 'l‘llF is used. This solution can be cast as a film into a water bath which causes rapid coagulation of the ose acetate polymer and densification of the film. These films may be processed on roll to roll equipment and many layers are wrapped to create a spiral wound membrane filter for use in micro—filtration, ultranfiltration, gas filtration, or reverse osmosis applications. In place of cellulose acetate, common polymers used include polyamides, efins, polysulfones, polyetliersulfones, nylidene fluoride, and similar engineered thernioplastics. It is also possible to extrude hollow fibers into the aqueous solution to create membrane fibers through the phase inversion process that are ltnown as hollow—fiber membranes commonly used for dialysis, reverse s, and desalination applications. ionizer in some embodiments, the PnCDP particle matter is incorporated into membrane material to enhance the performance of the ne materials. For example, it is possible to have present in the aqueous coagulation bath a small quantity of P—CDP particle dispersion that will become incorporated into the dense ns or porous portions of the membrane during the phase ion process. A, second manner to incorporate the PCB? particles into the membrane is the incorporation of a small amount of wellvdispersed particles into the organic on of the membrane polymer that become encapsulated in the membrane following coagulation. Through each of these methods? the production of P-CDP loaded polymer forms may be enabled. in various embodiments, such as micro—filtration, ultra-filtration, and reverse osmosis, the P—CDP particle incorporation acts to enhance the n'iicropollutant ren'ioval of the membrane system. {@0129} in some embodiments, the PCB? particles are incorporated into melt extruded th ermoplastics (cg fibers and molded . Having access to small diameter dry powder P~ CDP particle material of low polydispersity enables its incorporation into melt processed polymer forms including fibers and molded parts. Typical thermoplastics of use include hyleneterephthalate, yesters, polyolefins, and ides. Typical extrusion temperatures are between 250—300 "C and therefore l’uCDP particle stability to those temperatures either under air (most preferred) or inert here is required. Single or twin— screw extrusion is used to blend and mix the powdered material at elevated temperatures under shear with the thermoplastic in up to five weight percent. Once adequately mixed, the blended components can be extruded through small round or otherwise shaped orifices and drawn to produce fibers bearing the particulate matter linear densities ranging from l to 20 denier per filament. A common particle added to most thermoplastic fibers is titanium dioxide added to whiten and deluster the fiber. The l’nCDP particles will be added in a similar fashion. ln the most ideal embodiment, the l’nCDP les will migrate to the surface of the fibers and bloom due to their higher surface energy such that a portion of the particles are present and accessible by the vapor or liquid phase. in other embodiments, instead of extruding the polymer melt through small orifices, it can be blow molded or otherwise melt processed to produce a plastic part. This plastic part will also bear the PnCDP particles that bloom to the surface and become active for the removal of small molecule micropollutants leg. anionic Mill’s) from the vapor and liquid phase. {lilililll} The P—CDP of the present disclosure can be supported or formed into a variety of shapes (or formmfactors) suitable for various applications.

The high amine and urea content provides a polyn'ier that is structurally different from the prior art and which is more advantageous for the rernoval of anionic niicropollutants (cg. PEAS). {$19158} tal analysis data shows that final CD:TDl ratio is l:8~l :lO when a feed ratio of lt4 is used, which suggests the presence of excess 'l‘Dl units on cyclodextrins. Additionally, 1H NMR spectroscopy shows the presence of~-—Cl-l3 protons resulting from the arnine functionalized phenyl unit (Fig. 3}. Amine groups can be quantified using the "(ll-l3 peak at ~l.9 ppm that ates from a ‘TDl unit with amine groups on it. The ratio of that integration to total integration of -—-—Cl-l3 pealrs provide the percentage of TDls with amines.

Fig. l shows the results at 0.5 and 48 h, with polymers made from 4,4’—MDl and 2,4~‘T‘Dl being particularly effective at PFAS sequestration. Although faster l lrinetics was observed in the 'l‘Dl polymer (SLul _ 010A), the MDl polymer 20~3) also had good removal performance over the course of 48 h. Polyrners obtained from 6 eq. of Hill and MDl did not t good removal of either PFOA or PFOS, most lilrely due to the formation of hard gel during their synthesis which renders binding sites ssible in the particle.

While BPA uptake was not ed, MO uptake was significantly improved, from ~30% for TFN-CDP to >99% for TFN-CDP+. As ed, TFN-CDP+ polymers demonstrated significantly less affinity towards positively charged molecules such as methylene blue compared to P (Table 9; Fig. 7). Encouraged by this preliminary data, TFN-CDP+ was tested for the removal of PFOA and PFOS at environmentally relevant concentrations.

Furthermore, TFN—CDP-r is still synthesized in one step and the amount of ve charges incorporated can be easily modified by changing the amount of choline de used in the reaction. {(130165} Experimental: 1}ij (l g, 0.88l mniol), TEN (l .06 g, 5.286 nimol), lizCGs (2.44 g, l7.62l , choline chloride (0.37 g, 2.643 mmol), and 5.4 mL HzO/DMSO (2:3, v/v') were added to a 20—mL scintillation vial equipped with a ic stir bar. The mixture was stirred at 60 °C for 2f: h. Additional t (1 mL) was added after the first hour of stirring. After 20 h, 10 mL of water was added and stirred to disperse the polymer for 30 min. After filtering, the crude product was transferred to a fuge tube. The sample was washed with hot methanol ("\rllOmL) three times (3 0 min for each cycle). After decanting ol, Dl water (~30 mL) was added. 1 M HCl was added dropwise while stirring the sample until the pH was stable between 3—4. The crude product was further washed two more times with hot methanol (~49mL). The final ol wash was filtered under vacuum and product was dried at 80 "C overnight. {anion} Testing PFOA and PFOS removal performance — PFAS adsorption experiments were performed to measure the removal performance of different TFN—CDP+ polymers. In an effort to facilitate the screening process for a large number of polymer formulations, adsorption kinetics were performed using a mixture of l2 PFASs in nanopure water. The understanding of adsorption cs is essential as it reveals information on adsorbent doses and required contact times that are relevant for treatment processes. in addition to providing insights into PFOA and PFOS uptake, this panel study also allowed assessment of performance against other PFASs such as GenX and short- and long~chain PFASs in order to determine pectrum PFAS removal lities of these polymers. The results summarized in Fig. l show the removal percentages for each PFAS at 30 mm and 48 h contact times. These experiments were conducted in triplicate with ~l pph of each of the 12 PFASS in re water at a polymer loading of l0 mg/L. l experiments were also performed with no adsorbent and reported removal percentages are corrected for any losses observed during the control ments. All polymers were sieved with 230 mesh. {(130167} lmpressively, the two derivatives of TFN—CDP-l- (namely, 1343443363 and MBul ~037 made from 3 and 6, eq. of choline chloride. respectively) demonstrated the best removal performance of all polymers tested, with near complete removal of all l’FASs in the panel. Over min, MB—l—Q37 displayed effective removal of GenX and short~chain l’FASs, in addition to PFOA and PFOS. presumahly due to its higher quaternary ammonium loading (Fig. 2 9 {till 163} After performing initial screening under the panel study, removal assessments were narrowed to select polymers using a binary mixture of PFOA and PFOS ("l‘ahle 10). ln this specific task, all tion experiments were conducted with 0.5 pph of PFOA and l pph of PFOS at a polymer loading of lt‘i mg/L. Control ments were performed with no adsorbent and all measurements were done in triplicate. Samples from each on were taken for analysis at predetermined time points: 0, 0.5g 2., 4., 8, and 24 h. Polymers selected for these measurements were SL—l—Gl 0A, (TDD, Mild—036 (TFN+CC), and hClB—l —03’7 C). All the polymers tested trated great removal of PFQS over 24 he but l 0A (Till) and two TFNMCDPWL derivatives displayed high l (>90%) in only '30 min. As for removal of PFOA, even though Mid—01014 (TDT) showed similar performance to the panel study; l‘vle—l —036 and M84 ~03? outperformed the other two polymers in terms of both kinetics and removal capacity over 24 h.

EPA and MO were chosen as model compounds to study the uptake of neutral and negatively charged micropollutants, respectively, for understanding the adsorption mechanism in e chloride— modified 'l‘lFNuCDP polyniers. Furthermore, fitting the mi cropollutant adsorption data as a function of concentration to a Langmuir model ions l and 2) enables the determination of the thermodynamic parameters of the als tested.

By fitting the experimental adsorption data using nonlinear regression, quad and KL parameters can he obtained. Single~site Langmuir model was determined to he suitable for fitting the EPA adsorption data, whereas MO adsorption data were best fitted using the dual~site model. {(130172} For choline chloride—modified ’lFNmCDl’ polymers, rnaximurn M0 capacities (9mm) of 46.6 and 78.8 mg/g were found for rs made with l5 and 3.0 equivalents of choline chloride, respectively, for the first tion site (Table l I, Fig. 8). The second adsorption site (aiming) displayed rnaximurn e capacities of 37.3 and 33.0 nig/g, both of which are quite similar to the maximum capacity of unmodified TFNuCDP (grim 37.6 mg/g). This data, as well as similarities hetween K1; and K12 values, suggests that the second adsorption site in choline chlorideuniodilied TEN—CD? polymers is associated with MG adsorption within the CD cavity.

The comparison between K1.,1 and K112 values also indicates a significantly stronger first adsorption site which likely originates from the interaction of anionic MO molecules with quaternary ammonium sites. BPA adsorption data were fitted using a singlemsite Langmuir model and similar K1 values were determined, for all three polymers, indicating the presence of similar adsorption site for a neutral molecule. Maximum EPA capacities of llZl and, l00.l nig/g were found for the two choline chlorideunodified 'l‘FN—CDP rs and a ty of l06.l mg/g was ined for the unmodified 'l'li‘NnCDl’ (Table ll; Fig. 9). y, these saturation uptake values are in good agreement with the density of CD sites in these polymers. This observation also suggests that EPA adsorption occurs within the cavity of CDs.

Air bubbling was observed after the diisocyanate addition, presumably due to the moisture in the reaction system. After about l min when huhhling suhsided, the vial was . After 3 h, the reaction was d by adding l0 rnL of methanol and turning off the heating. White powder product precipitated out after methanol addition. The e was erred to a 50 ml; opylene centrifuge tube. After fuging, the solvent was decanted and the crude product was washed with water (4t) mL X 2 times), and methanol (40 ml; X 2 times). ln each wash cycle, the mixture was stirred for 30 min and followed by centrifuge. In the final cycle, the product in methanol was filtered under vacuum and dried at 80 °C overnight. Fig. l0 shows a 1ll NMR spectrum of a choline chloridenmodified B—CD—TDI polymer made with l:6:l molar lents of B—Cl):'l'l)l:choline chloride in 5 mL of DMF at 80 0C for 3 hours. The appearance of urethane and urea groups at 775—96 ppm indicates successful incorporation of e chloride into the polymer. The following chemical shifts are also found in thelH l‘leR spectrum: 6.75—7.75 ppm ns from the aromatic ring in TDD; 556 pm (protons from ~OH groups that are attached to C2 and C3 in SSE); 4,8 -5 ppm (protons that are ed to Cl in 5431)); 4.25—4.75 ppm (protons from ~08 groups that are attached to err in BmCD); All ppm (protons from —O~CH2— groups in e chloride); 3.5—4 ppm ns that are attached to CZ~C6 in B~CD); 3.3—3.5 ppm (protons from water); 3.18.2 ppm (protons from €83 groups in choline chloride); 2.5 ppm (DMSO); l.9~2.l ppm (protons from — CH3 groups in TDl); Peaks noted with star are from residual solvent. Fig. ll shows a comparison of a choline chloride—modified B-CD—TDE polymer and a DI polymer, with the key difference being the broad peak centered around 3, l3 ppm. Sharp pealrs at all ppm and 3.l ~32 ppm originates from unreacted choline chloride. Fig. 12 shows a comparison between three choline cl'iloride-modit‘ied BwCD-TDI polymers with different choline chloride loading amounts, which supports the position that with increasing amount of choline chloride, the pealr intensity increases at 3. l 3 ppm. {98174} in accordance with the synthetic procedure outlined above, a variety of rs were made with varying stoichiometric equivalents as shown below in Table l2. Furthermore, the polymers were tested for their PFOA uptalre. The results show that by incorporating choline chloride into a ButiD—E‘Dl polymer, cationic charge can he added to the polymer in a controlled fashion, resulting in PFQA uptake increasing from 70% to 99% when compared to Shul u0l 0A polymer ('lahle l2).
