Cu(II) removal from aqueous solutions: A Review

Copper is a widely known toxic as well as poisonous metal to the living organism with a permissible concentration of 50 μg/litre in aqueous solutions. It is necessary to provide a suitable, environment friendly and cost effective copper removal process to save the world. The biosorption technique was found to be an effective method for the treatment and removal of copper from aqueous solution. The use of eco-friendly and low-cost biosorbent as well as biosorbent regeneration are the effective means of using biosorption techniques for the removal of copper from aqueous solutions. However, this review present the various techniques used in the treatment and removal of copper from aqueous solution with emphasis on biosorption technique.
