Research Abstract

A nobel electrodialysis prosess has been developed for the recoery of rare-metal elements and regeneration of EDTA and Cu from their EDTA complexes solution. In the experiments of recovery of Sr and Zn from their EDTA complex soution, Sr and Zn were selectively separated from their EDTA complexes. Electrodialysis treatments accompanied by electro-chemical reaction were also studied in order to regenerate EDTA and Cu from their complex solution. The electro-chemical reaction was successfully proceeded, and the formation rate of EDTA and disappearance rate of EDTA-Cu were increased with increasing current density. All the experimental results were analyzed with a mathematical model which was considered electro-chemical reaction on the cathode, ionic flux in the cation-exchange membrane, and material balances of EDTA, EDTA-Cu, and sodium. The simulated results agree well with experimental results.
