Abstract
A novel cyclodextrin polymer with ultra-fast adsorption performance is provided. A cyclodextrin polymer having a three-dimensional network structure is obtained by mixing and crosslinking a cyclodextrin with a rigid crosslinking agent and a non-rigid crosslinking agent at a certain temperature. The polymer is capable of adsorbing a plurality of organic pollutants in water at an ultra-fast rate, and the polymer after adsorption is easily regenerated by simple washing at a normal temperature, and is repeatedly used without causing a decrease in adsorption performance.
