摘要
采用吸附试验方法,研究了滑石对含铅废水的处理效果,探讨了滑石用量、反应时间和溶液p H值对吸附效果的影响,绘制了吸附等温线,并分析机理。结果表明,滑石对水中Pb(Ⅱ)的吸附效果良好,吸附结果均能较好的符合Langmuir和Freundlich等温吸附模型,吸附类型为物理吸附,以表面吸附为主。
The effect of treating wastewater containing lead with talc was studied by adsorption method,The in- fluences of talc dosage, reaction time and pH value of the solution on the adsorption effect were investigated, the ad- sorption isotherms drawn, and the mechanism analyzed. The results showed that the adsorption effect of talc on Pb （ Ⅱ ） in water is good,the adsorption results accord with the Langmuir and Freundlich isothermal adsorption model quite well. The adsorption is a kind of physical adsorption,and predominantly surface adsorption.
