摘要: 通过EDTA-2Na对壳聚糖进行酰化改性制备EDTA-壳聚糖，采用单因素试验结合正交试验确定EDTA-壳聚糖的最佳制备条件，并将其与壳聚糖盐酸盐、壳聚糖季铵盐、羟丙基壳聚糖、壳聚糖乳酸盐对Cd²⁺的吸附性能进行对比.结果表明：1）EDTA-壳聚糖的最佳制备条件为EDTA-2Na与壳聚糖的质量比2：1，pH值5.5，EDAC浓度40 mmol/L，反应时间16 h.在此条件下进行验证试验，得出EDTA-壳聚糖对Cd²⁺的平均吸附率达53.04%.2）对比试验表明，在同一条件下，EDTA-壳聚糖对Cd²⁺的吸附效果，均优于其他壳聚糖衍生物.

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.
