| 摘 要： | 对海泡石原矿进行酸、热联合改性。采用单因素实验,对改性海泡石处理Cu2＋、Pb2＋、Zn2＋多金属废水进行了研究。结果表明,经过0.9 mol/L的盐酸浸泡活化29 h,再经过450℃高温焙烧的改性海泡石,在初始pH为7.0、35℃的条件下,对初始浓度50 mg/L Cu2＋、Pb2＋、Zn2＋的吸附率可达80%以上,吸附特征可用Freundlich吸附等温式很好地模拟。

| Abstract: | The natural sepiolite was modified with acid and heating.The Cu2＋,Pb2＋,Zn2＋ mult-metals wastewater was treated by the modified sepiolite through single-factor experiment.The results showed that the concentration of acid was 0.9 mol/L,the time of acid-activation was 29 h,and the temperature of heating-activation was 450 ℃.When initial pH was 7.0,initial temperature was 35 ℃,the removal rates of Cu2＋,Pb2＋,Zn2＋reached above 80%,and the absorptive behavior can be related to the Freundlich isothermal adsorption equation. |
