Study of eco-friendly agricultural wastes as non-conventional low cost adsorbents: A review


G. Islamuddin*, M.A. Khalid and S.A. Ahmad

Water scarcity will be a key issue for the sustainable development of a country in future. Now India is facing a water crisis and coming years it is estimated that India's population will be suffered from severe water scarcity. In this paper, we study, review and compare the characteristics of various types of agricultural wastes as natural adsorbents. A vast assortment of ease regular adsorbents have been examined for their capacity to expel different sorts of toxins from water and wastewater. On the off chance that these agricultural wastes could be utilized as best adsorbents, it will give favorable position to ecological contamination. There have been attempts by scientists to investigate the adsorption capability of non-conventional, naturally-occurring agricultural wastes in treatment of different effluents. In India alone in excess of 400 million tons of agricultural wastes is produced every year, which incorporates bagasse, stalk, coir substance, rice husk etc. Investigating use of the agricultural wastes for use as adsorbents can give reasonable options in contrast to the treatment of domestic and industrial effluents.
