Preparation, Characterization and Determination of Antimicrobial Activities of Cupric Oxide (CuO) Nanoparticles Using Citric Acid Toe Yi Yi Myint The present research deals with a study on the synthesis and characterization of cupric oxide nanoparticles. The nanoparticles were synthesized by sol-gel method using citric acid. Magnesium nitrate and copper nitrate were used to obtain homogeneous solution. The solution was heated and stirred to obtain gel powder. The powder was dried in an oven at temperature of 105˚C to obtain constant weight. The resulting sample was thermally heated in muffle furnace at temperature of 500˚C for four hours to get required nanoparticles. The prepared nanoparticles were characterized by Energy Dispersive X-ray Fluorescence (EDXRF) and X-ray powder diffraction (XRD). Then determination of antimicrobial activities of the nanoparticle was carried out by Agar Well Diffusion Method. According to the XRD analyzed data, the average particle size of CuO nanoparticle was 23.21nm. 2020-12-01 https://meral.edu.mm/records/9312
