The influence of several variables on the removal process was studied such as a type of electrodes, initial pH, initial concentration of Cr+6 ions, electrolysis time, sodium chloride concentration and current density. The experimental results showed that the removal efficiency of Cr+6 ions was more effective when using iron electrode comparing with the aluminium electrodes. The maximum removal of Cr+6 ions was 96.58% at pH 6.0, initial ion concentration 40 mg/L, electrolysis time 15 min, sodium chloride concentration 2 g/L, and the current density 30 mA/cm2.Cr+6 ionsElectrocoagulationHeavy metal removalWastewaterSymposium Proceedings
