摘要
用壳聚糖(CTS)与硝酸铅在酸性介质中反应制备壳聚糖-Pb(Ⅱ),用X射线光电子能谱(XPS)、红外光谱(IR)对壳聚糖、壳聚糖-Pb(Ⅱ)进行结构表征,探讨壳聚糖对Pb2+的吸附机理。研究表明,Pb2+与壳聚糖的—NH2发生了配位反应,而其中的—OH未参与反应。
Coordination compounds of chistosan (CTS) with Pb ( Ⅱ ) were prepared in acid system. The coordination compounds were characterized by X-ray photoelectron spectrum (XPS) and infrared spectrum (IR),and further to study the adsorption mechanism. The results show that Pb^2+ coordinates with the --NH2 groups on CTS and the --OH groups have not take part in reaction.
