Abstract:
By complexation reaction with water-soluble carboxymethyl chitosan and Ca 2+ ?Fe 2+ ?Zn 2+ in solution,the metal complexes of Ca 2+ ?Fe 2+ ?Zn 2+ were preparated.The effects of various factors:reaction time,etmperature,substitution degree of carboxymethyl group,ionic strength and pH value on the reaction were investigated.The results showed that the optimum reaction condition was pH 5~7,time 10 min,the complex capacity of CMCS for metal ions increasing with the substitution degree of carboxymethyl group,decreasing with the ionic strength of solution.
