| 摘 要： | 研究了高分子重金属絮凝剂(PEX)对镍离子螯合能力的大小,以含镍水样作为处理对象,通过一系列试验证明:PEX对镍离子的螯合能力强,生成的螯合体溶解度小,对低浓度的镍离子废水处理效果好。废水中一定量的EDTA或Ca2+的存在,不仅不会影响PEX对镍离子的去除,而且会大大促进这一过程。

| Abstract: | The chelation capacity of macromolecule heavy metal flocculant(PEX) to nickel ions was studied,a series of experiments were made with nickel-containing water as treatment target,the results testified that: PEX had a great chelation capacity to nickel ions,the solubility of the chelate was small,which showed a good effect on treatment of wastewater containing low concentration of nickel ions.The existence of some EDTA or Ca2+ in wastewater not only had little influence on the removal of nickel ions with PEX,but also promoted the said process greatly. |
