Description

Flat mixed-matrix forward osmosis membrane and preparation based on metal organic framework ZIF-8 Method
Technical field
The present invention relates to flat forward osmosis membrane of a kind of macromolecule and preparation method thereof, and metal is based on more particularly to one kind Organic backbone ZIF-8 flat mixed-matrix forward osmosis membrane and preparation method.
Background technology
The scarcity of water resource and the water pollution of getting worse turn into the bottleneck for restricting social progress and economic development, new water Source is developed and effluent sewage recycling also turns into global question of common concern.Because seawater resources are extremely abundant on the earth, And substantial amounts of effluent sewage is produced, desalinization and sewage recycling turn into the strategic choice for solving water resources crisis.Many Desalinization and sewage recycling technology in, membrane separation technique is one of best selection.Asked as to solve this key Topic and be born low energy consumption, the positive infiltration technology of high Water Sproading rate is into desalinization and the research emphasis in sewage recycling field And focus, to solving the problems, such as that shortage of water resources has important strategic importance.
Positive infiltration (forward osmosis, FO) is a kind of membrane separation technique driven by film both sides osmotic pressure, just It is increasingly subject to pay attention to, related theory and application study achieve larger progress, and are successfully applied to desalinization, at waste water The field such as reason, food medicine, the energy.At present, common forward osmosis membrane mainly has cellulose acetate film, polybenzimidazole membrane, gathered Acid amides composite membrane etc., degree of commercialization is not high to be mainly a lack of forward osmosis membrane of good performance and suitable driving liquid, and just oozes Permeable membrane is the key point of whole positive process of osmosis.The close phase of structure of high performance forward osmosis membrane and its material character and film Close, it is seen that the membrane material and forward osmosis membrane preparation method of function admirable are particularly important.Common forward osmosis membrane preparation method bounded Face polymerization, double selection tunics prepare three kinds of method and nanofiltration membrane modifying.Concentration difference in positive osmosis composite membrane prepared by interfacial polymerization Polarize more serious;Double selection tunics effectively reduce interior concentration polarization, but preparation technology is complex;NF membrane Modified Membrane is to list The rejection and water flux of valency salt are relatively low;Therefore, it is necessary to develop new forward osmosis membrane preparation technology to improve forward osmosis membrane Separating property and the feasibility of industrialization.
The last century 60's, foreign countries are started the research of positive infiltration technology, entered using existing reverse osmosis membrane or NF membrane The application study that row is just permeating, as a result proves that existing reverse osmosis membrane or NF membrane are difficult to use in positive process of osmosis, but simultaneously Performance and membrane material, the membrane structure for demonstrating forward osmosis membrane are closely related;Then, all multimembrane scientific workers have started positive infiltration The basic research of film preparation.Result of study shows, can be excellent with processability by selecting suitable membrane material, film-forming process Forward osmosis membrane.The research of the positive infiltration technology in China is started late, and the current country aligns the research of infiltration technology, either film system Standby or membrane process research, still in the exploratory stage.Some film researchers explore the preparation of cellulose family forward osmosis membrane Condition, influence of the various factors to forward osmosis membrane performance is have studied, but not yet prepare just oozing for commercially viable function admirable Permeable membrane;The preparation and application study of forward osmosis membrane still shoulder heavy responsibilities.The studying enlightenments of early stage we, changed using blending technology Property membrane material, be expected to improve water flux, salt-stopping rate, mechanical performance and the anti-fouling performance of forward osmosis membrane, and be easily achieved production Industry.Patent of invention ZL201410770001.4,201510245514.8 and ZL201410769752.4,201510245504.4 Nano titanium oxide and graphene is respectively adopted and prepares flat and doughnut forward osmosis membrane with acetyl cellulose blend, it is made The separating property and permeance property of standby forward osmosis membrane have obtained raising by a relatively large margin;Patent of invention 2017100954795, 2017100954780th, 2017100954846 more excellent performance is prepared for using functionalized carbon nano-tube and acetyl cellulose blend Forward osmosis membrane;But by selecting suitable material, the separating property and permeance property of prepared forward osmosis membrane can still be carried out Further to improve, satisfaction is commercially produced and application demand.
It is new that metal organic framework (Metal-Organic Frameworks, MOFs) is that a kind of latest developments are got up Material, also known as metal organic complex polymer, it is to pass through coordination group by the organic ligand and metal ion of oxygen-containing, nitrogen etc. Fill the porous material of the infinite network structure formed.Compared to traditional inorganic porous material, MOFs materials possess zeolite, activity The unrivaled premium properties of the inorganic porous materials such as charcoal, CNT, its Micropore volume are higher by several than above-mentioned porous material Times, and have the characteristics that duct is variable, steady chemical structure.These excellent characteristics cause MOFs materials in gas storage, water Body pollution thing adsorbing separation, gas catalysis etc. have huge application prospect.Metal organic framework is as a kind of new Organic-inorganic hybrid material, the organic ligand in its structure are favorably improved the affinity between MOFs particles and polymer substrate, It is preferable mixed substrate membrane containing nano-grade molecular sieve dispersed phase.Therefore, suitable MOFs materials and acetyl cellulose blend are such as prepared into mixed-matrix Forward osmosis membrane, it is expected to while high water flux, salt-stopping rate is obtained, also make forward osmosis membrane product that there is stain resistance, this is just The research and development and application of permeable membrane material provide new thinking.
How while hydrophilic nmature is obtained, make forward osmosis membrane that there is resistance tocrocking again and keep the stabilization of water flux Property, this is the problem that film scientific worker is thinking and studied always in recent years.The present invention is improving mixed-matrix just using ZIF-8 The research of the structure and permeance property, separating property of permeable membrane, both at home and abroad there is not yet document report.
