Removal of Zink from Waste water by using mangifera Indica Peel

Abstract

With the commencement of industrial development mankind has witnessed various environmental issues in the society. This industrial development has not only brought growth and prosperity, but eventually disturbed the ecosystem. One of the influences is visible, in the form of water pollution. In the present study, heavy metal contamination of water bodies has been discussed. Effluents from factories contains huge amount of heavy metals in them. Chemical oxidation, chemical precipitation, membrane separation, ion exchange, electro dialysis, reverse osmosis etc. are some of the modern methods adopted in treating waste water contaminated with heavy metals. However these methods are expensive, energy intensive and give toxics as by products.Adsorption has been investigated as a cost-effective, energy efficient, method of removal of heavy metals from wastewater. In the present study, Mangifera indica peel is used as low-cost adsorbent. It has been identified as an effective adsorbent in the removal of Zinc from waste water.
