Description

A kind of manufacturing method of threadiness heterogeneous Fenton catalyst
Technical field
The invention belongs to the design of functional fibre material in textile material field and manufactures, are related to a kind of fibrous out-phase The preparation of Fenton catalysts, specially one kind can catalytic oxidant (such as hydrogen peroxide, ozone) quickly, efficient oxidation Decompose a variety of dyestuffs, the reusable, manufacturing method of fiber that is easy to separate with water body.The manufacturing method integrated use is heavy Technologies, the gained fibers such as shallow lake polymerization, wet spinning, penetrating power promotion, iron ion complexing, heat cross-linking can be used for waste water from dyestuff etc. The processing of the water body containing organic matter.
Background technique
It is constantly progressive with the rapid development of society with industrial, the water pollution problems being on the rise is to the existence of the mankind Safety constitutes significant threat, becomes the major obstacles of human health, economy and society sustainable development.And textile printing and dyeing industry is made For typical highly water intensive industry, production process process is sufficiently complex, need to consume nearly hundred million tons of water every year, thus generate a large amount of dyestuff Waste water causes serious environmental problem.(Guangwei Zhang, Idzumi Okajima, Takeshi Sako, Decomposition and decoloration of dyeing wastewater by hydrothermal Oxidation, The Journal of Supercritical Fluids, 2016,112 (1): 136-142;Terinte N, Manda B M K, Taylor J, et al, Environmental assessment of coloured fabrics and Opportunities for value creation:Spin-dyeing versus conventional dyeing of Modal fabrics, Journal of Cleaner Production, 2014,72 (6): 127-138).Waste water from dyestuff at It is point sufficiently complex, have the characteristics that water is big, change of water quality is big, high organic content, coloration height, biodegradability are poor, and contain more Organic matter with bio-toxicity or " three cause property " (carcinogenic, teratogenesis and mutagenicity), direct emission can bring living environment High risks, while the waste of water resource is caused, and as state and society is to the pay attention to day by day of environmental protection requirement, it is traditional Dye waste water treatment method have been unable to meet production and environmental protection requirement, therefore, at present dye wastewater treatment field there is an urgent need to Seek efficient, inexpensive processing material and technology (Ay F, Catalkaya E C, Kargi F, A statistical experiment design approach for advanced oxidation of Direct Red azo-dye by Photo-Fenton treatment, 2009,162 (1): 230-236).
Since the 1980s, countries in the world environmental science and technology has been caused to generate the high-level oxidation technology that OH is mark The attention on boundary, due to high-level oxidation technology have the characteristics that oxidability by force and it is without secondary pollution, so be considered as processing water Middle hardly degraded organic substance most has the technology of application prospect.Compared with other high-level oxidation technologies, Fenton method is due to having reaction Rapidly, oxidability is strong, good decolorizing effect and the features such as strong flexibility, it is considered to be is widely used at present and with development potential One of dye waste water treatment method.Fenton system passes through Fe2+With H2O2Reaction generates the OH with high reaction activity, And OH has the Strong oxdiative ability for being only second to fluorine, can be produced with oxygenolysis organic pollutant, intermediate as oxidation process Object can induce subsequent chain reaction, and the substance of certain difficult for biological degradation is made to be transformed into the substance of easy biological treatment, and The chromogenic or auxochrome group for destroying dyestuff, makes it lose color development ability, so that coloring matter is made to degrade, organic pollutant is thorough It is harmless to turn to carbon dioxide and water.Chemical reaction condition needed for Fenton system is mild, easy to accomplish, and oxidation reaction does not have Have introduce other poisonous and harmful substances, for waste water from dyestuff improvement open new approach (Ayoub K, N é lieu S, Hullebusch E D V, et al., TNT oxidation by Fenton reaction:Reagent ratio effect On kinetics and early stage degradation pathways, Chemical Engineering Journal, 2011,173 (2): 309-317).
Currently, Fenton reaction system mainly includes the homogeneous and big reaction system of out-phase two, to further increase organic matter Removal effect, by optics, ultrasonic technology and electrochemical techniques etc. be dissolved into Fenton reaction in form novel homogeneous Fenton reaction system (Babuponnusami A, Muthukumar K, A review on Fenton and Improvements to the Fenton process for wastewater treatment, Journal of Environmental Chemical Engineering, 2014,2 (1): 557-572;Han Z, Dong Y, Dong S, Copper-iron bimetal modified PAN fiber complexes as novel heterogeneous Fenton catalysts for degradation of organic dye under visible light Irradiation, Journal of Hazardous Materials, 2011,189 (1-2): 241-248), but it is common homogeneous Fenton reaction system is still that Fenton method processing dyestuff is useless with the absolute predominance in terms of cost and technical feasibility Common reaction system when water.But for common homogeneous Fenton reaction system, because its only at lower pH It can be effectively carried out, need to adjust waste water repeatedly pH value to acidity, increase processing cost, and homogeneous Fenton reaction system Catalyst it is miscible in waste water in the form of an ion, homogeneous catalyst and reactant, reaction product mixing, cause using rear catalysis Agent is difficult to separate, and generates a large amount of iron cements, and post-processing is complicated, waste reaction resource, and improves use cost, limits homogeneous The application of Fenton reaction system.
With in Fenton reaction system catalyst research deeply and the enhancing of mankind's environmental consciousness, by divalent or Ferric ion, other ions and compound ion are supported on certain carrier, form heterogeneous Fenton catalyst, different Phase Fenton reaction system can handle waste water from dyestuff within the scope of wide pH, i.e., organic molecule is adsorbed onto catalyst table first Face, in active component and H2O2Under the action of, organic molecule decomposes, and the product desorption after degradation simultaneously returns in solution, in turn Pollutant process is completed, and heterogeneous Fenton catalyst can be separated with aqueous systems easily, and then can be repeatedly used, In During this, since the iron ion amount of elution is few, therefore a large amount of iron cements (Zeng X, Lemley A T, Fenton will not be generated Degradation of 4,6-Dinitro-o-cresol with Fe2+- Substituted Ion-Exchange Resin, Journal of Agricultural&Food Chemistry, 2009,57 (9): 3689-3694).It follows that out-phase Fenton reaction system had not only remained the advantages of homogeneous Fenton reaction, but also significantly compensated for its deficiency, was greatly simplifying processing On process base, it can greatly expand wastewater treatment range, it has also become an important development of Fenton method processing organic wastewater Direction will also play a positive role in the treatment of waste water, have fabulous application prospect.
Currently, heterophase Fenton catalyst mainly includes load typed iron catalyst, iron powder or iron ore catalyst etc..Load Sections catalyst can preferably solve the secondary pollution problems of iron ion in homogeneous Fenton system, and carrier is either have Airborne body, is also possible to inorganic carrier, and Nafion membrane is a kind of cation exchange being made of perfluorinated sulfonic acid anionic polymer Film has many advantages, such as that heat-resisting, corrosion-resistant and intensity is high, but since Nafion membrane is expensive, also needs to consider film in practical application Oxidation resistance and (Wu Wei, Wu Chengcheng, Zhao Yaping, heterogeneous Fenton technology degradable organic pollutant the problems such as fouling membrane Progress, Environmental science and technology, 2010,06:99-104);In addition, some macromolecular organic compounds such as sodium alginate Deng also can be used as immobilization carrier (Cruz A, Couto L, Esplugas S, et al., Study of the contribution of homogeneous catalysis on heterogeneous Fe(III)/alginate Mediated photo-Fenton process, Chemical Engineering Journal, 2016,318:272-280), But such carrier is difficult to be subjected to the oxidation corrosion of OH.In inorganic material, aluminium oxide is a kind of common catalyst carrier, molecule Sieve be also commonly used as catalyst carrier (Zhou Yaliang, Huang Dongyue, the type and progress of Fenton's reaction technology, Guangdong chemical industry, 2013,40 (1): 74-74);Clay, main component are kaolin, frequently as iron ion carrier (Li Huanyu, it is heterogeneous The progress of Fenton reaction treatment organic pollutant, building and budget, 2015,06:47-50), using inorganic material as carrier Heterogeneous Fenton catalyst there is at low cost, the advantages such as specific surface area height and adsorption capacity are strong, but catalyst preparation mistake Journey is complicated, and fine catalyst is difficult to recycle, and application is restricted.Iron powder or iron ore catalyst are primarily present in nature ore In, magnetic material has magnetic iron ore, maghemite, perovskite, lepidocrocite and spinelle etc., and non-magnetic material has bloodstone and needle iron Mine etc., iron powder and these mineral materials itself can be with H2O2Constitute Fenton system come degradation of organic substances (Khataee A, Taseidifar M, Khorram S, et al., Preparation of nanostructured magnetite with plasmafor degradation of a cationic textile dye by the heterogeneous Fenton Process, Journal of the Taiwan Institute of Chemical Engineers, 2015,53:132- 139;Munoz M, Pedro Z M D, Casas J A, et al., Preparation of magnetite-based Catalysts and their application in heterogeneous Fenton oxidation-A review, Applied Catalysis B Environmental, 2015,176:249-265), but ferriferous oxide Fenton reaction system It is affected by pH, in acid condition, the dissolution of iron ion can induce H2O2OH is generated, but the iron ion dissolved out is eventually given birth to At iron cement, cause secondary pollution, and ore iron type is less and limited source, limit it and further apply.
In the above context, novel carriers material is researched and developed, keeps iron ion or iron oxide securely and equal It loads evenly on it, is easily isolated solid-liquid while improving catalytic performance;On the other hand, in the same of selection suitable carrier When iron species are modified, be made excellent combination property heterogeneous Fenton catalyst, become great real value. The present invention selects suitable polymerized monomer first, using precipitation polymerization method synthesis rich in the poly- of specific functional groups carboxyl, hydroxyl etc. Object is closed, then the polymer of synthesis is dissolved in water soluble alkali aqueous solution, using this solution as spinning solution, with inorganic acid aqueous solution It for setting medium, using wet spinning technology spinning fibre, and is handled through special process, after assigning loose and porous structure to forming Fiber, to reduce osmotic resistance when iron ion adsorbs and fixes, thus make within the limited time fibrous inside be full of iron from Son, iron ion load capacity increase, through thermal crosslinking treatment after, make to be dehydrated between amount of activated group carboxyl and hydroxyl and form friendship Join network structure, cross-linked network structure fetter iron ion, along between carboxyl, hydroxyl and iron ion strong complexing and The constraint of fiber surface acts on, and is securely joined with iron ion more in fibrous inside, iron ion washes when greatly reducing application De- amount assigns finished fiber fabulous reusability, becomes heterogeneous Fenton catalyst truly, together When in thermal crosslinking treatment, selected using atmosphere in high temperature furnace, realize and the existence form, form, crystal form of iron species are carried out Modification, further enhances its catalytic activity, to the processing for water bodys containing organic matter such as waste water from dyestuff, for reaching for above-mentioned water body New processing material is developed in mark discharge.
