Application of Electrocoagulation for the Removal of Heavy Metals from Industrial Wastewater: A Review

Abstract

Heavy metal ions like arsenic, chromium, lead, zinc and copper are usually present in wastewater that is a main concern for environment which is harmful. This review is done to gather the related research article or literature from 2008 to 2020 on subjects relevant to electro-coagulation process in industrial waste water for the elimination of heavy metal ions. Different working factors like pH, electrode material, current density, reaction time have been studied.
