Comparing of Zinc Ion Adsorption on Several Minerals

摘要：

Many natural minerals have strong absorbability,ion exchangeability and expansibility.This paper studied the Zn2+ adsorption on the several minerals,and analyzed the Zn+ adsorption mechanism.The results show that adsorption progress is a two-phase process that experienced a rapid reaction first and a slow reaction then.The mechanism of removal of heavy metal ions by minerals is hydrolysis of heavy metalions induced by hydration on surface of minerals and electrostatic force between heavy metalions and hydrocolloid particles.
