Adsorption of Pb(II) from wastewater by natural and synthetic adsorbents

Water pollution is a major concerned to the human health. Most of the global surface water is contaminated with heavy metals, has become a serious problem today. Particularly, Pb is highly toxic and directly associate with health risk such as damage to kidney, liver and central nervous system. In this review article, removal of lead utilizing various adsorption methods is described. Such as, natural (e.g. shells and peels corncobs, mushrooms, dairy manure, orange, apple, custard apple, peanut, eggshells, banana, eggplant, fish scales algae); activated carbon (e.g. sugar cane, orange peel, chicken feather fruit seed and bentonite); nano-composite, magnetic nanomaterials, polymer composite; chitosan, cellulose, clay, lignin, calcite, resin and chemicals are presented.
