摘　　要：探讨了在不同矿物投加量、不同振荡时间、不同Cu2+浓度、不同矿物颗粒细度和不同pH条件下,钠基膨润土、膨胀蛭石和沸石3种粘土矿物对Cu2+的吸附效果,并比较了3种粘土矿物对Cu2+的吸附差异性。结果表明:对Cu2+的吸附效果依次为钠基膨润土>沸石>膨胀蛭石;较高的pH有助于粘土矿物对溶液中Cu2+的吸附,但考虑到实际操作的其他因素,不能把pH调得过高。in this paper, the absorption effect of three clay minerals to Cu^2＋ are studied in different conditions such as the amounts of mineral, shaking time, the concentration of Cu^2＋ , the granularity of mineral and the pH of solution, and the three clay minerals are Na - bentonite, expansibility vermiculite and zeolite. The absorption differences of these three clay minerals to Cu^2＋ are also compared. The results show that the absorption effect of three clay minerals to Cu^2＋ follows the order of Na - bentonite 〉 zeolite 〉 expansibility vermiculite; higher pH value helps to absorb the Cu^2＋ in the solution, but pH value can＇t be too high considering the other factors in the actual operation.
