Removal of Heavy Metal (Chromium) From Aqueous Solution using Acacia Arabica Wood (Black Babul)

Abstract

Heavy metals become a serious problem to society in the view of water pollution. Polluted water causes many disorders in human beings, animals and plants also. The concentration of heavy metals increases mainly due to the activities like mining, agricultural activities and disposal of industrial waste products. Most of the activities releases heavy metals like Mercury (Hg), chromium(Cr), arsenic(Ar), thallium (Tl), nickel (Ni), lead (Pb), and cadmium (Cd). Separation of these heavy metals from water many treatment methods are available like chemical precipitation, ion exchange, membrane separation, electrodialysis, ultra-filtration, nano filtration, coagulation, flocculation, floatation and adsorption. Adsorption is the best method out of all these methods. Activate carbon is normally used as adsorbent but it is expensive. Black babul wood is the cheapest and abundant available in nature. So treatment of heavy metals black babul wood used as adsorbent. In this article, effect of parameters like process time, initial concentration, adsorbent dosage, adsorbent particle and temperature on separation of Chromium from aqueous solution is studied.
