Experimental Research of Spouted Particulate Electrodes on Removal of Copper Wastewater

Abstract:

In this research, heavy metal copper was chosen for this study, with its sulfate solution simulated wastewater, using spouted particulate electrodes to purify wastewater and recycle metal copper. Experimental studied the effects on different conditions of electrodeposition, such as pH, constant current, copper ion concentration, the size of the cathode particle and nitrogen sparging. The results showed the optimum conditions were that pH was 3.0, constant current was 10.0A, the size of cathode particle was 1.8mm and with nitrogen sparging. In particular, nitrogen sparging not only reduced dissolved oxygen in wastewater to prevent the metal back to solution, but also handled the problem of low current efficiency due to concentration polarization and electrochemical polarization.
