An experimental studyon the effect of manganese dioxide & ferric oxide nano-particles for sewage water decontamination

Abstract

The vision of this paper is to investigate and introduce a technique to decontaminate, one of the most essential commodities of life that is, water. The requirement of water for an individual varies from a minimum of 8 liters per day for drinking and cooking to about 20-50 liter per day for other daily needs. Unfortunately, about half of a billion people face the problem of water scarcity throughout the year. The treatment of wastewater namely sewage water can reduce these concerns however; the traditional methods of treatment are not efficient enough to completely remove the emerging pollutants. In this paper an experimental study was conducted for the effect of nano-sized materials on the purification of sewage water. As a matter of fact, various nano-materials have been prepared and used for the removal of contaminants from water. Herein the mechanism of adsorption was taken in to consideration were manganese dioxide and ferric oxide nano-particles were utilized as an adsorbent for decontamination of sewage water. The nano-materials were synthesized by means of planetary ball mills and characterization was done through scanning electron microscope. Then the prepared nano-particles were introduced in to the pre-tested water samples for contaminant adsorption. It was observed that the nano-materials can adsorb contaminants like zinc, magnesium, cadmium, chlorides & sulphates to some extent. In addition to this, the treated water shows excellent water quality standards.
