Abstract

The batch removal of heavy metals lead (Pb), zinc (Zn) and copper (Cu) from industrial wastewater effluent under different experimental conditions using hydrogen peroxide was investigated. Experimental results indicated that at pH 6.5, pre-treatment analysis gave the following values: Pb 57.63 mg/l, Zn 18.9 mg/l and Cu 13.9 mg/l. Removal of heavy metals was optimum at pH 7.6, a temperature of 30oC, 1.5% hydrogen peroxide concentration and 60 min holding time, reducing the amounts of Pb, Zn and Cu by 83.5, 85.5 and 82.23%, respectively.
