Abstract:
The removal of hexavalent chromium (Cr+6) ions from simulated wastewater was
investigated by using batch electrocoagulation. 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.
