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