摘要
利用电导实验技术,研究壳聚糖(CTS)、水杨醛改性壳聚糖(RS-CTS)对金属离子Cu2+、Zn2+吸附的动力学特征,结果表明该吸附是以化学吸附为主要特性的单分子层吸附,通过计算不同情况下的吸附速率常数,初步分析其吸附机理。
The kinetic characteristics of adsorbing Cu^2+ and Zn^2+ by chitosan (CTS) and modified chitosan (RS-CTS) were studied by conductometric method. The study showed that the adsorption was a chemical one with single molecular layer as main characteristics. In the study, the adsorption rate constant under different conditions was derived through calculation, and adsorption mechanism Was analysed preliminarily.
