复合高铁酸盐处理含Ag(CN)_2^-、Zn(CN)_4^(2-)配离子模拟废水的研究

Study on Disposal of Simulate Waste Water Containing Ag(CN)_2^- and Zn(CN)_4^(2-) by Composite Ferrate

用复合高铁酸盐处理含Ag(CN)2-和Zn(CN)42-的配水,并讨论了不同反应条件对处理效果的影响.结果表明,重金属氰根配离子、重金属离子和氰离子的去除率都能达到96%以上,在水中的残留量都远低于国家排放标准.

Water Containing Ag（CN）^-2 and Zn（CN）^2-4 is disposed by composite ferrate in this paper. The effects different outside conditions on disposal results are discussed . The results indicate that the removel rate of heavy metal complex ion with CN^- , heavy metal ion and CN^- all reached above 96% and that their residual quantityies are lower than the letting criteria of country after disposal.
