Porous cyclodextrin polymer |
| abstract |
The disclosure provides an amphiphilic porous cyclodextrin polymer: cyclodextrin is grafted with aromatic molecules, and then alkylated with biphenyl benzylidene chloride and p-xylylene dichloride through Friedel-Crafts reaction, to obtain a porous polymer with an ultrahigh specific surface area. This material has very high adsorption capacity and can be reused for simple regeneration. Because the hydroxy groups of cyclodextrin are partially retained, the hydrophilicity of the material surface is improved, allowing the adsorption rate to become faster. Moreover, there are a variety of adsorption mechanisms, and hydrophobic and hydrophilic pollutants can be adsorbed simultaneously. |
