摘　　要：利用静态吸附方法 ,研究两性离子交换树脂处理含锌的废水。实验结果表明 ,酸的存在对树脂吸附Zn2 + 影响很大 ,酸度越大吸附量越小 ,盐的存在在一定范围内有利于Zn2 + 的吸附 ,但超过一定浓度则不利于Zn2 + 的吸附。The treatment to Zincic waste water by amphoteric ion exchange resin was investigated by static adsorption method.The experimental results show that the existence of acid has a big effect on the adsorption of Zn 2+ on the resin.The adsorption decreases with the increase of the acidity.The existence of salt within a ceratain concertration is propitous to the adsorption of Zn 2+ ,but makes against to the adsorption of Zn 2+ when it exceeds a certain concentration extent.
