Removal of Heavy Metals from Water/Wastewater Using Agricultural and Industrial By-Products as Adsorbents

Water used in Industries creates a waste water having metals which creates a hazard for our environment because of introducing various pollutants such as heavy metals into soil and other resources. The adsorption process is being widely used by various researchers for the removal of heavy metals from water/waste water and the activated carbon remains an expensive adsorbent. Therefore there is an urgent need to introduce possible Agricultural and Industrial By-Products as Adsorbent for the Removal of Heavy Metals from Water/Wastewater. In this study the ability of different adsorbents to remove heavy metals like Chromium, Copper, arsenic, cadmium, and lead has been investigated.

The objectives of this study is to contribute in the search for low cost, eco friendly adsorbents and utilization of various agricultural and industrial by-products such as Sugarcane Bagasse, Rice husk Activated carbon derived from Coconut shell, Activated charcoal derived from Coconut shell, Coconut husk carbon, Coconut shell carbon, Tea waste, Chitosan/Chitin, Chitosan coated oil palm shell charcoal, Dye treated Cassava Mesocarp, Green algae (Ulva Lactuca) Sago waste, Coconut husk, coconut husk and palm pressed fibers, carbon prepared from Casurina Equisetifolia, Zeolite, Biocharcoal for the Removal of Heavy Metals from Water/Wastewater.
