Application of Cationic Cyclodextrin in Wastewater Treatment

Cationic cyclodextrin belongs to chemically modified cyclodextrin, which is a kind of cyclodextrin ether derivative containing amine group and positively charged on the nitrogen atom by etherification of various organic amine compounds containing halogenated or epoxy groups and hydroxyl groups in cyclodextrin molecules. Cationic cyclodextrins have the characteristics of high dispersibility and solubility, high stability and weak retrogradation.

Cationic cyclodextrin in industrial wastewater treatment, with the electronegativity of the impurity reaction package, flocculation, in the printing and dyeing industry, cationic cyclodextrin can be from the printing and dyeing wastewater adsorption dye;In the paper industry, cationic cyclodextrin can flocculate the suspension liquid and deink the waste paper liquid. At present, some countries and regions have adopted cationic cyclodextrin and negative polyacrylamide to treat wastewater.

Cationic cyclodextrin as an industrial grade commodity in the application of sewage treatment has great applicationPotential.
