The absorption of organic matter on the sorbent
In this experiment, test and organic matter is adsorbed from aqueous metal solution using different adsorbents.The absorption of test Agent is:Activated carbon (Aldrich, 20-60 mesh), microspheroidal PMMA (measure the poly- (first of mean molecule quantity~120,000 by GPC Base methyl acrylate), Aldrich) and microspheroidal PBMA (poly- (Isobutyl methacrylate) of mean molecule quantity~130,000, Aldrich) (PMMA and PBMA are shown as PXMA in fig. 17) and crosslinking PS (DowexL-493, Aldrich)。PS(Dowex L-493, Aldrich) be 20-50 mesh bead, it has 1100m2/ g table Area, 4.6nm average pore size and the crushing strength of 500g/ pearls.
Staticadsorption experiment is carried out in 20mL screw cap vials.Contain 4M CuCl2(H2O)2, 1M CuCl and 2M NaCl Aqueous stock solutions doped with a small amount of ethylene dichloride (EDC), chlorethanol (CE), dichloro acetaldehyde (DCA) and trichloroacetaldehyde (TCA).The content of organics of the solution extracts the aqueous solution by using 1mL EtOAc and analyzes the organic matter of EtOAc extracts Concentration is analyzed.6mL stock solutions stir as shown in figure 17 show at 90 DEG C together with different amounts of sorbent material Indicated special time in figure.After filtering, extraction and GCMS analytic approach by organic phase are analyzed in the handled aqueous solution Content of organics.It has been observed that the gradually increase of the amount with sorbent material, the drop of the content of organics gradually increased It is low.Highest reduction amount is observed under crosslinking PS.
In this experiment, the power of regeneration of adsorbent is tested as follows:With given sorbing material (DowexOrganic matter 495-L) is repeatedly adsorbed from the solution containing Cu, with cold water and the hot wash material, drying should Material, is then re-used for absorption by the material after washing.The result of the experiment is shown in Figure 18.It has been observed that absorption property is Make still to be very similar to unworn material after second regenerates.It was additionally observed that, adsorb right after organic matter with Dowex materials Ultraviolet (UV) measurement of Cu concentration does not show significant changes.Using not used material, it was observed that about 10% it is total The reduction of Cu concentration, and 1-2% Cu concentration reduction is only observed using regrown material.These results of study indicate that polymerization is inhaled The advantage of the Reusability of enclosure material, because polymeric material adsorbs organic matter from the solution of copper ions, and even multiple Using not retaining substantial amounts of Cu ions after circulation.So sorbent material can regenerate after its adsorption capacity exhausts, and again Sorbent material after life can be reused for absorption.
Then Dowex is evaluated in dynamic adsorption post (figure 19 illustrates)495-L materials, to set up The transmission time under the flow conditions.Contain 511g CuCl2(H2O)2, 49g CuCl, 117g NaCl and 500g water deposit it is molten Liquid is doped with EDC (1.8mg/mL), CE (0.387mg/mL), TCA (0.654mg/mL) and DCA (0.241mg/mL).Pass through extraction Take and analyze initial organic concentration with GCMS analytic approach.91-94 DEG C of hot reserve solution is pumped by filled with 13.5g Dowex V495L post (diameter 1.25cm, length 15.2cm).The temperature measured in exit is 78-81 DEG C. Flow velocity is 18mL/min.After 60 minutes, charging is converted into hot DI water from stock solution, starts regeneration cycle.With shown in Figure 20 Curve map in indicated time interval sampling.Extraction and content of organics of the GCMS analytic approach to sample by organic phase Analyzed.It has been observed that CE, followed by DCA, with the earliest transmission time, is followed by TCA.EDC observes the latest saturating Spend the time.
The regeneration curve of organic matter is followed and absorption identical order:Clean the CE of absorption first with hot water, followed by Be DCA.The next organic compound for cleaning adsorbent is TCA, is finally EDC.It has been observed that absorption and desorption curve and when Between may be influenceed by parameters such as flow velocity, temperature, column dimensions.These parameters can be used for optimization and enter electrochemistry electricity The technology of organic matter is removed before pond from outlet stream.
