| Popis: | Well structured nano-sized Copper oxide has been prepared by simple reflex method for different pH concentrations. The Prepared samples are subjected to various characterization studies such as XRD, SEM, UV–Vis spectroscopy and FTIR spectroscopy inorder to investigate their crystallite structure, morphology, optical properties and functional vibrations. The structural analysis of prepared CuO samples revealed a monoclinic crystalline structure. The morphology of CuO samples reveals spindle shaped with size distribution ranging from 70 nm to 90 nm. The sample prepared at pH 5 seemed to possess the expected qualities to apply for antibacterial activity. The prepared samples consisting of various amounts of CuO nanoparticles are developed to study the antibacterial activity for different strains of bacteria. The results showed that at the optimized pH concentration, CuO samples calcinated at 400 °C exhibited improved antibacterial activity for E. coli bacteria. |
