dc.description.abstractZinc oxide and manganese oxide nanoparticles were synthesized by chemical method using poly ethylene glycol (PEG) as a surfactant, zinc sulphate (ZnSO4. 7 H2O) & manganese sulphate (MnSO4. H2O) as a precursor molecules. Different characterization techniques were used for the determination of size and morphology of synthesized nanoparticles such as X-ray diffraction photometer (XRD) and Transmission electron microscopy (TEM). All the results confirmed that the surface of nanoparticles have sufficient compatibility with surfactant. These nanoparticles were tested for its antimicrobial activity against various bacterial strains. The nanoparticles were also used for the removal of toxic organic pollutants such as dye Methylene Blue under UV irradiation. The different operational parameters such as the initial concentration of the dye, weight of the photo catalyst, and pH on the photo catalytic degradation of the dye were investigated. Results proved that both nanoparticles act as very good catalyst for the effective degradation of Methylene Blue in the presence of sunlight. The as synthesized nanoparticles were also found to inhibit the activity of 1, 1-Diphenyl-2 picrylhydrazyl (DPPH) free radicals effectively. This research work revealved a simple and fast method for the preparation of ZnO & MnO nanoparticles with no need for expensive materials or complicated treatmentsen_US
