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 Ni2 + and Cu2 + ,effective removal of heavy metals in waste water.%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 pH 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。
