摘要
在静态条件下 ,研究了膨润土对重金属离子 (如 Zn2 +、Cd2 + )的吸附与交换。结果表明 ,膨润土对重金属离子具有较强的吸附性能 ,p H值是影响吸附的主要因素 ,离子交换和表面络合反应是主要吸附形式。
The adsorption of cadmium and zinc ions on natural bentonite heat treated at 110℃ or 200℃ , from aqueous solution at 30℃ has been studied. The results show that samples have a high and a medium affinity for cadmium and zinc ions respectively, and pH value is an important factor to affect adsorption,and ion exchange and surface complex are main adsorbing form.
