Removal of Toxic Metals from Industrial Wastewater by using Natural Adsorbent

Abstract

Heavy metal pollution has become one of the most serious environmental problem nowadays. Numerous investigation have been conducted for removing heavy metals by utilizing agricultural waste which have caught more attraction for its advantages and removal efficiency. Treatment process for removal of toxic metals include Bioadsorption, Precipitation, Ion Exchange, Reverse osmosis, Electrochemical treatment, Membrane Filtration, Evaporation, Flotation, Oxidation. Instead of using commercial materials, we have worked on inexpensive materials such as natural and agricultural products. It is evident from survey that bioadsorption is widely applied for the treatment of metal contaminated wastewater. Bioadsorption techniques are eco-friendly best solution, for removing heavy metals from wastewater. Different Cortex fruit wastes, including banana, kiwi peels, groundnut shell as an adsorbent is used for removing toxic and heavy metals like Cu, Zn and Cr.
