Removal of Heavy Metals Using Low Cost Adsorbents

Abstract

Much attention has been made towards adsorbent materials to be used in heavy metal removal from polluted water and various techniques are applied such as chemical, physical and biological techniques. This study was designed for using less expensive and much frequently available materials (mango peels, Neem leaves & coconut husk) to remove iron, copper and cadmium from water. Current data show that all adsorbents used are capable of removing copper, iron and cadmium ions at significant capacity. Furthermore, coconut husk had higher capability than mango peel and neem leaves.
