Treatment of Waste Phosphoric Acid Containing Metal Ions by Electrodialysis

Abstract:

The electrodialysis mehtod was used to treat waste phosphoric acid containing Al and Mo ions in this study. The feasibility study of elctrodialysis for treatment of the waste phosphoric acid containing metal ions was investigated. The voltage, solution concentration and feed temperature mainly affect electrodialysis of the phosphoric acid containing Al and Mo ions. Higher voltage and feed temperature are beneficial for desalination of Al and Mo ions. At least, 30% of Al ions and 7% of Mo ions can be removed from the phosphoric acid by using the CMX/AMX, CM1/AM1 and CMX-SB/ACS ion-exchange membranes. An electrodialysis process seems to be a promising process to treat waste phosphoric acid containing Al and Mo ions.
