摘要
通过动态淋溶和静态吸附实验,研究了矸石溶出液中氟、锰在土壤中的吸附特征。结果表明,土壤对氟、锰的等温吸附式分别符合Temk in和Freund lich方程,土壤对氟、锰的饱和吸附量分别为39.3 mg/kg和8.6 mg/kg;采用分层填充土壤对氟、锰元素的吸附控制效果更好,其动态截留量分别为13.8 mg/kg和3.2 mg/kg。
F、Mn adsorption characteristic of gangue leaching solution in soil are studied through the dynamic and static adsorption experiments.The result shows F and Mn model of isothermal adsorption match Freundlich and Temkin equation,the soil adsorption capacity of F and Mn is 39.3 mg/kg and 8.6 mg/kg;filled with layered soil F、Mn adsorption control better,dynamic interception are 13.8mg/kg and 3.2 mg/kg.
