Water Soluble cyclodextrin polymer (MW＜10000) obtained by cross-linking copolymerization of cyclodextrin has an amorphous space network structure, and the water-soluble cyclodextrin polymer has a high water solubility (>50%), which retains the original cyclodextrin. On the basis of the cavity, the outer space of the cyclodextrin in the network structure can also bind the guest molecules, so it shows a far better inclusion and solubilization ability than the monomer cyclodextrin and its derivatives.
The application of Water Soluble cyclodextrin polymer (MW＜10000) in water treatment field: it has a high ability to remove micro-pollutants in water, especially for inorganic heavy metal ions (Pb2 + , Cu2 + , Cd2 + , Zn2 + ) and phenol and aniline. removal effect.
The water-soluble polymerized cyclodextrin synthesized in alkaline medium not only retains the original cavity structure and can continue to envelop many guests to form host-guest inclusion complexes, but also introduces a large amount of C-O- C ether bond, which can complex many inorganic heavy metal ions (Pb2+, Cu2+, Cd2+, Zn2+).
This characteristic of cross-linked polymer is applied to the treatment of simulated water samples. The experimental results show that the water-soluble polymerized cyclodextrin retains the original hydrophobic cavity and a large number of hydroxyl groups on the outside, and can form with organic molecules and metal ions, respectively. Host-guest inclusion complexes and complexes are conducive to contact and sedimentation with pollutants. It has high removal capacity for micro-pollutants in water, especially for organic phenols and amines in water samples, and the polymer packed column can be regenerated by elution. Therefore, water-soluble polymeric cyclodextrins have certain application prospects in the field of sewage treatment as water purification agents.
The unique structure and strong encapsulation ability make water-soluble polymerized cyclodextrins as new functional materials receive extensive attention in the fields of sewage treatment, environmental protection, and chiral drug separation.
