| 中文摘要: |
| 应用水溶性的羟甲基壳聚糖与Ca^2 、Fe^2 、Zn^2 进行络合制备金属配合物，探讨反应时间、温度、羧甲基取代度、溶液离子强度、pH等反应条件对络合的影响，考察金属配合物的性质。结果表明：络合反应的最佳pH值为5－7；室温下反应10min络合量趋于饱和；羧甲基壳聚糖对各金属离子络合能力随羧甲基取代度的增大而增强，随着体系的离子强度增大而减弱。 |
| English Summary: |
| 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. |
