The results showed that the % decrease in Cr concentration is highest at the Cu-Cu electrodes with a time of 2 hours and a 15V voltage is equal to 71.73% while for the Cu-C at the time of 3 hours and a voltage of 10V % reduction of Cr by 58.64%. And for the Cu-Pt electrodes at 2 hours and voltage 20V % reduction of Cr by 49.63%.
