The reduction of the chromium concentration from effluents to a permissible limit before discharging them into streams and rivers is important for human health and the environment. Adsorption is an effective method for removing chromium, solving the sludge disposal problem. Pectic-rich (orange peel, grapefruit peel and lemon peel), and lignocellulosic biomaterials (rice husk, soya husk) are low cost adsorbents for CrIII removal from aqueous solutions.
