Abstract
The Photocatalytic degradation and anti microbiological studies of a Hospital Waste Water (HWW) using synthesized Zinc oxide nanoparticles (ZnO Nps) form the core area of the present study. The synthesized Zinc oxide nanoparticles (ZnO Nps) were characterized using XRD, FE-SEM (Scanning electron microscope) studies. Chemical Oxygen Demand (COD) was considered as a potent physicochemical parameter to study photocatalytic degradation of HWW under solar irradiation. Bacterial strains of E. coli and B. subtilis were considered for the antibacterial assay whereas Phytophthora and A. flavus was investigated to study the antifungal property of Zinc oxide nanoparticles (ZnO Nps). HWW is a laden with high concentrations of pharmaceutical metabolites, disinfectants, heavy metals, gene-toxic reagents as well as infectious microbes which when discharged without any pre-treatment pose a great threat to the environment. The results indicate that ZnO NPs exhibited good photocatalytic and antimicrobial activity and can be used for treatment for HWW and its administration.
