蒙脱石对溶液中重金属的吸附特性研究

Study on adsorption of heavy metals in solution with montmorillonite

采用镍和铜作为溶液中的吸附质,探讨了蒙脱石对重金属的吸附性质,并通过实验,研究了p H值、蒙脱石用量、反应时间等因素对吸附Ni2+和Cu2+的影响,有利于废水中重金属物质的有效去除。

The nickel and the copper are adopted as adsorbate in the solution and discusses on the surface properties of montmorillonite and ad-sorption properties for heavy metals. pH,the dosage of bentonite,reaction time and other factors are studied through experiments on the adsorp-tion of Ni^2 ＋ and Cu^2 ＋ ,effective removal of heavy metals in waste water.
