摘要：

在微波辐射下制备了壳聚糖/Y分子筛复合材料（CTS/Y），考察了其对Cu²⁺吸附性能。结果表明：Y分子筛质量分数为6%时CTS/Y对Cu²⁺吸附量最大；随交联剂用量增大，树脂吸附量先增加后降低；溶液pH为5.2时对Cu²⁺吸附量最大。动力学研究表明吸附过程符合准二级动力学模型。

Abstract:

A novel chitosan-based composite(CTS/Y) made from chitosan and Y molecular sieve has been prepared under microwave irradiation and its adsorption capacity for copper ions is investigated. The results show that the adsorption capacity of CTS/Y reaches the maximum when the content of Y molecular sieve is 6%. With the increase of cross-linker dosage, the adsorption capacity of Cu²⁺ on CTS/Y increases firstly and then decreases. The adsorption capacity reaches the maximum when pH of Cu²⁺ solution is 5.2. The kinetic research shows that the adsorption process conforms to pseudo-second-order kinetic model.
