The present research investigated the synthesis of a novel adsorbent by combining Moringa oleifera and silver nitrate (AgNO3). The chemical components of the pre-adsorbent and adsorbent material were characterized using Fourier Transform infrared Spectroscopy (FTIR), while the equilibrium adsorption capacity (Qe) obtained for Copper (Cu), Manganese (Mn) and iron (Fe) were 0.042, 0.039 and 0.041 respectively. These results indicated that the adsorbent was able to remove Mn more than Cu and Fe from the aqueous salt mixture. However, the results observed for the biofilm experiment revealed that the M. oleifera-AgNO3 biocidal action was effective in deactivating oxidizable components in the wastewater system after 8 days. The above findings have demonstrated that the synthesized M. oleifera-AgNO3 adsorbent would be effective in cleaning-up waste streams contaminated with microbes and trace metals.
