The cell comprised of aluminum electrode as anode and stainless steel electrode as cathode. Thirty experiments and one hundred fifty sample lab tests were carried out in this research to study the effect of the mentioned paramet cr5 on the efficiency of the removal process.Experimental work of this research proved a higher efficiency about 95 % removal of zinc from wastewater at 1.4 mA! cm in alkaline media atpH equal and Mmperature 45°C.
