摘 要：
研究了CCMKGM对Cu2+的吸附热力学行为,用FTIR和RAMAN对吸附产物进行了结构表征,同时考察了不同解吸剂对吸附于CCMKGM上Cu2+解吸效果的影响。结果表明,CCMKGM主要以配位的形式吸附Cu2+;CCMKGM对Cu2+的吸附行为同时符合Langmuir和Freundlich等温方程;吸附为自发的、吸热的熵增加过程。

摘 要：
In this paper the adsorption thermodynamics properties of CCMKGM with Cu2+ were investigated.The structure of adsorption products were characterized by the FTIR and RAMAN.The influence of different elution on desorption was stud-ied.The results showed that CCMKGM adsorbed Cu2+ mainly by complication,the experimental date fit well into the Lang-muir and Freundlich adsorption isotherm.The adsorption was a spontaneous endothermic process of increased entropy.
