【Abstract】 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.更多还原
