离子交换法处理含络合铜废水的实验研究

An Experimental Investigation of the Treatment of Complexed Copper-containing Wastewater by Ion-exchange

摘要: 采用阴离子交换树脂，对离子交换法分离稀土工艺中产生的Cu-EDTA络合废水的处理，进行了研究，结果表明，本方法能有效浓缩回收Cu-EDTA和游离EDTA，并有望返回到稀土生产中去。

Abstract: An negative ion-exchange resin is used in this study to investigate its treatment of the Cu-EDTA-complex wastewater fro m rare earth separating process by ion-exchange.The experimental results show that the Cu-EDTA and free EDTA can be concentrated and recovered by the method of this study, and it is expected to be reused in the process of rare earth separating.
