Abstract
A wide variety of chelating organic ion exchange resins and inorganic ion exchangers were tested for the removal of nickel and zinc from waste effluents from metal plating plants. Best performances were found to be exhibited by three chelating resins, sodium titanate and an active carbon impregnated with oxine. For most of these exchangers, the batch separation percentages were 99.9% or higher at pH above 5. Column experiments showed that the most effective exchanger for nickel was an inorganic ion exchanger, sodium titanate, and for zinc an aminophosphonate resin, Duolite ES 467.
研究了多种螯合有机离子交换树脂和无机离子交换剂对金属镀锌厂废水中镍和锌的去除效果。三种螯合树脂、钛酸钠和氧浸渍活性炭表现出最好的性能。在pH大于5的条件下，大多数交换器的批分离率达到99.9%或更高。柱式实验表明，无机离子交换剂钛酸钠是镍最有效的交换剂，氨基膦酸树脂doolite ES 467是锌最有效的交换剂。
