SWITCH TO GREEN METHODS FOR WASTE WATER MANAGEMENT

The proposed research work is indebted to the green solution for mitigation of water pollutant that was discharge from industries. In this modern era, water pollution caused by heavy metals is a serious concern to improve the quantity of drinking water. To solve this problem, an environmental friendly Zinc oxide (ZnO) photo catalyst has developed that is suitable for removal of arsenic impurities from wastewater originating from industries. ZnO is less hazardous metal oxide in compared to other mixed or metal oxide as increase in Zinc concentration has minimum impact on living organism, hence it is referred as green synthesis in this work. The physical characterization of zinc oxide performed using Scanning electron microscopy, Fourier Transform Infra-Red spectroscopy, Thermo gravimetric analysis, and X-ray diffraction analysis. To study the catalytic performance of ZnO, we have observed different O.D. values (at 380nm) for a series of ZnO solution ranging from control to 10%, 20% and 30% of ZnO. The photo catalytic activity was studied for 24 h with 10% and 20% ZnO (p H 7.8) at room temperature and it was found to be effective towards remediation of water pollution. It was found to be 78.46% in case of 10% ZnO and 78.04 % for 20% ZnO solution. Therefore, ZnO photocatalyst is proven to be an ecofriendly, and cost effective technique for water pollution mitigation
