摘要
采用高分子有机捕集剂与废水中的多种重金属离子发生螯合反应,生成稳定且不溶于水的金属螯合物来去除废水中的重金属离子。对4种捕集剂在不同pH值的条件下对含有汞、铜、镉、铅等重金属污水的去除效果进行了试验研究。结果表明,利用重金属捕集剂方法处理重金属废水的效率较高,有很好的应用前景。
Chelate reaction of organic trapping agent with several kinds of heavy metal ions can remove the heavy metals by forming stable and insoluble metal chelates. An experimental study was performed on the removal efficiency of mercury, copper, cadmium, and lead in heavy metal wastewater by four kinds of trapping agents under different pH values. The result indicates that the way using heavy metal trapping agent to treat wastewater of heavy metals is of high efficiency and good prospect.
