Abstract

In this research work, a polymer metal complex was obtained by mixing aqueous solution with polyvinyl acetate at a certain ratio and temperature. The pure polyvinyl acetate and the synthesized polyvinyl acetate mercury complex was characterized with FT-IR, Uv, XRD and XRF spectroscopy. The FT- IR which confirms the presence of the important functional groups like the carbonyl at 1699.7cm-1, the carbon to oxygen (C – O) at the 1060.9cm-1, and so on, it also showed points to the coordination of the metal to the polymer. The Uv spectral shows that there was a transition shift form the lower energy to the Higher energy level which shows that the metal coordinated the polymer and a increased wavelength band which is as a result of conjugation of the polymer. The XRF shows that the elemental composition of the pure sample and the complexed sample which has higher amount of the mercury salt present at the polymer metal complex which indicated that the mercury coordinated to the polymer. The XRD shows the three sharp peaks at the polyvinyl acetate sample which indicates the crystalline structure of the polymer and when compared to the complex the XRD spectral data has a highest peak showing the coordination of polymer with the metal.
