摘　　要：采用凹凸棒石粘土吸附剂对含Ni(Ⅱ)废水的处理进行研究。用粘土和活化土吸附剂处理含Ni(Ⅱ)水样,探讨了不同实验条件如吸附剂用量、灼烧时间、处理时间等对Ni(Ⅱ)吸附率的影响,得出了最佳实验条件。实验结果表明:用该吸附剂在最佳条件下处理含镍量为71mg/L的废水,可使Ni(Ⅱ)的残余浓度远远降低。The attapulgite clay as adsorbent was studied on treating waste water containing nickel(Ⅱ). The different experiment conditions how to have effect on adsorbing rate, such as the amount of adsorbent, roasting time, treating time, and so on were discussed. The best experiment conditions were drawn. The result indicated that remaining concentration of Ni(Ⅱ) in waste water treated by the adsorbent in the best onditions drop down the lowest.
