Lead Removal from Water by Low Cost Adsorbents: A Review
Lead is known to be toxic for human’s body systems i.e. nervous, digestive and skeleton system even if it is present in low levels. The rapidly increasing population is appending many problems concerning water pollution. The presence of lead metal in drinking water is of special concern because of its persistence and toxicity. In this review paper lead toxicity, its contamination in water and the effects of various factors on adsorption of lead, reaction kinetics, nature of link between lead and surface of media are described. The general prominence has been given on the utilization of different agricultural, industrial wastes and low cost synthetic oxides as adsorbents for the removal of poisonous lead from water.
