Abstract

Nano-sized manganese oxide and cadmium oxide were formed quantitatively via chemical routes, using calcination from an aqueous solution containing metal chloride as a precursor, to create polyvinyl alcohol and para-aminobenzoic acid complexes with the following formulae: [Mn (PVA)(P-ABA) (H2O)3] H2O and [Cd (PVA)(P-ABA) (H2O)3]. The synthesized complexes and metal oxide nanoparticles were characterized using elemental analysis, thermal analyses (TGA and DTA), FT-IR spectroscopy, XRD analysis, UV-vis spectra, and SEM and TEM electron microscopes. The kinetic and thermodynamic parameters (∆H*, ∆G* and ∆S*) for the Mn(II) and Cd(II) coordination compounds were calculated. The antimicrobial properties of the samples were assessed using five bacterial strains and three fungal strains. Three strains of (G+) bacteria, two strains of (G−) bacteria, one stain of yeast-like fungi, and two molds were used in this study.
