Description
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
The flat mixed-matrix forward osmosis membrane and preparation method of organic backbone MIL-53.
Background technology
The scarcity of water resource and the water pollution of getting worse become the bottleneck for restricting social progress and economic development, new water
Source is developed and effluent sewage recycling also becomes global question of common concern.Since seawater resources are extremely abundant on the earth,
And substantial amounts of effluent sewage is produced, sea water desalination and sewage recycling become the strategic choice for solving water resources crisis.Many
Sea water desalination and sewage recycling technology in, membrane separation technique is one of best selection.As this key issue of solution
And be born low energy consumption, the positive infiltration technology of high Water Sproading rate into sea water desalination and sewage recycling field research emphasis and
Hot spot, 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 paid more and more attention, relevant theoretical and application study achieves larger progress, and is successfully applied to sea water desalination, 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, gathers
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 it is particularly important that the membrane material and forward osmosis membrane preparation method of function admirable.Common forward osmosis membrane preparation method bounded
Three kinds of face polymerization, double selection tunic the preparation methods 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 process 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 process to improve forward osmosis membrane
Separating property and the feasibility of industrialization.
The sixties in last century, foreign countries start the research of positive infiltration technology, using commercialization reverse osmosis membrane or NF membrane into
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 at the same time
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, have studied influence of the various factors to forward osmosis membrane performance, 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 period 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 dioxide 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 excellent performance of the inorganic porous materials such as charcoal, carbon nanotubes, 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 help to improve 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, is expected to while high water flux, salt-stopping rate is obtained, also make forward osmosis membrane product have stain resistance, this is just
The research and development and application of permeable membrane material provide new thinking.
How while hydrophilic nmature is obtained, and make forward osmosis membrane that there is resistance tocrocking and keep the stabilization of water flux
Property, this is the problem that film scientific worker is thinking and studying always in recent years.The present invention improves mixed-matrix using MIL-53
The research of the structure and permeance property, separating property of forward osmosis membrane, both at home and abroad there is not yet document report.
