Abstract

EDTA-chitosan was prepared through the acylation modification between EDTA-2Na and chitosan. The preparation conditions of EDTA-chitosan were optimized by single factor test combined with orthogonal optimization test. The comparative analysis of Cd²⁺ adsorption properties of EDTA-chitosan was made with that of chitosan hydrochloride, chitosan quaternary ammonium salt, hydroxypropyl chitosan and chitosan lactate. The results showed that the optimum preparation conditions of EDTA-chitosan were as follows:the mass ratio of EDTA-2Na and CTS was 2:1, the pH value was 5.5, the concentration of EDAC was 40 mmol/L, and the reaction time was 16 h. The verification experiment under these conditions showed that the average Cd²⁺ adsorption rate of EDTA-chitosan was 53.04%. Moreover, the comparative experiment revealed that EDTA-chitosan had better Cd²⁺ adsorption effect than other chitosan derivatives under the same conditions.
