为了深入了解液/固体系Cu~(2+)、Zn~(2+)、Mn~(2+)在硅藻土表面的吸附行为与特性,为硅藻土在含重金属离子废水处理上的应用提供充分的理论依据,采用静态吸附试验对Cu~(2+)、Zn~(2+)、Mn~(2+)在硅藻土表面的吸附条件、性能、行为与特性进行了系统的研究.结果表明,硅藻土投加量和离子初始浓度对硅藻土吸附Cu~(2+)、Zn~(2+)、Mn~(2+)的影响均可归结为液/固比(液相离子与硅藻土的质量比)的影响,过高或过低的液固比均不利于吸附,硅藻土吸附Cu~(2+)、Zn~(2+)、Mn~(2+)所需的最佳液/固比分别为0.025、0.100和0.100.溶液初始pH值对硅藻土吸附Cu~(2+)、Zn~(2+)、Mn~(2+)的影响主要与溶液初始pH值与硅藻土...

In order to well understand adsorption behavior and characteristics of Cu~(2+),Zn~(2+),Mn~(2+) onto diatomite in liquid /solid system,and provide sufficient theoretical basis for application of diatomite in treatment of wastewater containing heavy metal ions,a series of static adsorption tests were conducted to investigate adsorption condition,property,behavior and characteristic of Cu~(2+),Zn~(2+),Mn~(2+) onto diatomite comprehensively. As result indicate,the effect of diatomite adding quantity and ion initial concentration on adsorption of Cu...
