Description
(1) technical field
The present invention relates to a kind of CO2Response dissaving polymer, and preparation method thereof, and as just permeating draw molten
The application of matter.
(2) background technology
Along with population increases and the acceleration of process of industrialization, the problem that World Freshwater Resources is deficient seems further serious, this
Threaten the survival and development of the mankind to a certain extent.The growing tension of freshwater resources makes increasing countries and regions
Greatly develop desalination technology, seawater desalination is obtained fresh water.Just permeating is that one is not required to impressed pressure and does driving force, and only
Relying on the membrane separating process that osmotic pressure drives, and fouling membrane situation is the lightest, it is possible to operation for a long time without
Clean, have good application prospect in the field such as desalinization, sewage purification.But, draw solute reverse diffusion and
Subsequent process draws the separation process of solute and water is loaded down with trivial details and the application that needs the shortcomings such as energy consumption to limit positive infiltration technology with
Development.
Drawing liquid and need to provide sufficiently high osmotic pressure, the most properity and pure water quality to film do not impact,
Additionally, simpler method also should be able to be used therefrom to isolate pure water, to obtain fresh water.Draw the solute in liquid be called draw molten
Matter, preferably draws solute and should possess following condition: 1. can produce higher osmotic pressure, i.e. should have higher in water
Dissolubility, thus should have less molecular mass;2. avirulence, can security presence in producing water;3. can stable existence,
I.e. can not be with film generation chemical reaction;4. during preparing pure water, it should can facilitate and liquid and pure water will be drawn economically
Carry out separating and can reusing.Select suitably to draw the important topic during liquid is always positive penetration study.
The solute that draws reported includes: salt such as NaCl, MgCl2、Al2(SO4)3、NH4HCO3;Saccharide such as glucose, really
Sugar etc..Jeffrey R.McCutcheon etc. (J.Membr.Sci., 2006,278,114 123.) report with NH4HCO3Solution is
Draw liquid, be applied to positive penetration sea water desalinization.Draw solute to separate by heat resolve NH with water4HCO3Reach to separate purpose,
Draw solute can not reuse.
It is the positive osmosis system drawing liquid that CN 203668144U discloses with hydrogel, and the hydrogel of employing is temperature sensitive water
Gel, utilizes solar energy equal energy source heating hydrogel to make it be dehydrated to water-purifying container.Solar energy needs sizable daylighting thermal-arrest
Face could meet use requirement, and device ground area is big, and materials are many, and cost increases;Atmospheric effect is relatively big, and solar energy has certain
Limitation.
Yufeng Cai etc. (Chem.Commun., 2013,49,8377) propose with having CO2The line answered with temperature double-bang firecracker
Type polymethylacrylic acid dimethylaminoethyl (PDMAEMA) is as drawing solute for desalinization.Line style PDMAEMA is drawn
Solute, is applied to positive penetration sea water desalinization.It is high that the PDMAEMA that molecular weight is high draws liquid osmotic pressure, but high molecular
PDMAEMA dissolubility in water is low and draws solute and can inversely be diffused into material liquid side, causes drawing solute loss.
(3) summary of the invention
For defect present in prior art, the present invention method by ATRP or RAFT, design and be prepared for one
There is CO2The dissaving polymer of response, and draw solute be applied to positive penetration sea water desalinization as just permeating.Polymerization
Thing dissaving structure has the characteristic such as highly dissoluble, low viscosity, and branched structure can efficiently reduce the reverse expansion of polymer
Dissipate.To drawing, liquid is passed through CO2, what polymer was dissolved in that water forms hyperosmosis draws liquid, and water flux is big, and reverse diffusion is little.Stop
Only after diffusion, to drawing, liquid is passed through N2, polymer meeting Precipitation, it is recovered by filtration polymer, just permeates for next time.
Draw the reclaimer operation simplicity of solute, energy consumption is low and can reuse.
