This study presents a constant-current electrolysis technique to remove Ni(II) efficiently from aqueous solution using an electrochemical cell. Three electrodes of aluminum, stainless steel, and graphite were used as cathodes, while rectangular graphite plates were the anode. The effects of solution pH values (0.37.0) and applied current density (I=100200A/m2) were investigated. Complete removal of Ni(II) ions was achieved within 12min using a graphite cathode at pH 1.0 and I=140A/m2, which had a current efficiency of 38%. Under the same conditions, more than 99% removal of Ni(II) was obtained from wastewater within 60min of electrolysis time.
