摘要
研究了壳聚糖对铬 ( )离子的吸附性能 ,测定了吸附等温线和吸附动力学曲线 .实验结果表明壳聚糖对铬 ( )离子有较强的吸附能力 .吸附率受 p H值影响较大 .在此基础上 ,通过 IR、UV、SEM等检测手段证实铬 ( )离子与壳聚糖之间发生了配位作用 .
The adsorption of Cr(Ⅲ)ion by chitosan has been investigated. It is found that chitosan has an excellent adsorption capacity for Cr(Ⅲ)ion, a nd it is highly influned by pH. The Cs-Cr complex formation is also proved by IR ,UV and SEM.
