Evaluation of modified Algerian clay as mineral adsorbent was done for its adsorbing capacity on copper (Cu) and Zinc (Zn) cations. The results obtained show a rapid kinetic adsorption for both metals (less than 2 h) following the pseudo-second order model with high elimination rates of 67.2 and 61.8% for Cu and Zn respectively. The adsorption isotherms analyzed with Langmuir model revealed a correlation with the experimental values. While the use of obtained chitosan at room temperature, as flocculent coagulant, accelerates the decantation of the colloidal particles in suspension generated after adsorption process.
对改性阿尔及利亚粘土作为矿物吸附剂的吸附性能进行了评价，研究了其对铜（Cu）和锌（Zn）阳离子的吸附能力。结果表明，两种金属的吸附动力学迅速（不到 2 小时），符合准二级动力学模型，Cu 和 Zn 的去除率分别高达 67.2%和 61.8%。用 Langmuir 模型对吸附等温线进行分析，结果与实验值相关。而壳聚糖在室温下作为絮凝剂使用，可加速吸附后悬浮胶体颗粒的沉淀。
