Removal of lead (II) from aqueous solution using low cost adsorbent: A review

Abstract

This review paper presents the various low cost adsorbents for the removal of lead (II) from contaminated water. If high concentration of lead present in aqueous solution causes many health diseases and it is toxic for human’s body systems i.e. skeleton, nervous and digestive system. The lead level must be maintained at certain limits. According to World Health Organization the permissible limit of lead concentration in drinking water is 0.01mg/lit. Low cost adsorbent used in adsorption process for removal of lead from contaminated water. It is easily available in our environment. Adsorption process is simple and cost effective method for removal of lead from contaminated water by using several low cost adsorbents.
