Research on lowlevel Cu(II)removal from water by organic sulfur(有机硫对水体中微量Cu(II)的处理研究)
针对重金属离子采用常规处理难以达标的问题,选用TMT、DTCR等有机硫和Na2S,对水中微量Cu2+进行深度处理研究.通过3种金属捕获剂的处理效果对比,最终选用TMT作为Cu2+捕获剂,重点探究了 pH值、反应时间、TMT投加量、温度等因素对TMT处理Cu2+效果的影响.结果表明,pH对Cu2+去除效果的影响最为显著,而其他因素的影响则有限.另外,在存在EDTA等络合剂的情况下,TMT对Cu2+处理效果并不理想,这一点通过络合常数和反应平衡常数的计算也得到了论证.通过本研究,可以为微量Cu2+等重金属离子的达标排放提供参考....
