【摘要】 采用沸石负载壳聚糖作为吸附剂,对溶液中铬(Ⅵ)的吸附平衡和吸附动力学进行了研究。结果表明,溶液中铬(Ⅵ)在沸石负载壳聚糖上的等温吸附数据符合Freundlich模型;吸附体系属于物理吸附,吸附状态属于多层吸附;吸附行为符合二级速率方程。
【Abstract】 The process of adsorption equilibrium and kinetics for chromium(Ⅵ) solution on zeolite loads chitosan adsorbents were studied.The results show that the adsorption data of chromium(Ⅵ) solution on the adsorbents fit with the Freundlich isotherm model;The adsorption system belongs to physical adsorption and the adsorption state belongs to multi - layer adsorption;The adsorption behavior fits with the second - order reaction rate equation.
