ABSTRACT
Water contamination poses a severe threat to public health and the environment, necessitating innovative approaches for its remediation. This study investigates the effectiveness of copper(II)oxide (CuO) and 6% manganese-doped copper(II)oxide (6%Mn doped-CuO) nanoparticles (NPs) in removing both bacterial and heavy metal contaminants from water. The contaminants of interest are Staphylococcus aureus and lead (Pb) ions. The NPs were synthesized using chemical co-precipitation method and characterized for their physicochemical properties with the use of FT-IR, SEM and XRD. The effectiveness of the synthesized NPs in removing lead from contaminated water was carried out using adsorption study. Also, the effectiveness of the NPs synthesized, was carried out using bacteriological analysis and turbidimetry. Average crystallite size of CuO NPs is 38.38nm with the highest crystallite size at 55.35nm and the least crystallite size at 19.67nm. Also, 6% Mn doped-CuO NPs were found to have a crystallite size of 31.19nm with the highest crystallite size at 45.74nm and the least crystallite size at 15.92nm. The results obtained showed that CuO NPs and 6%Mn doped-CuO NPs are polydispersed. The results obtained revealed that the synthesized NPs were efficient in removing Staphylococcus aureus and lead ions from contaminated water. However, it was observed that CuO NPs was more efficient in removing Staphylococcus aureus and 6%Mn doped-CuO NPs was more efficient in removing lead ions from contaminated water. On the overall, it was observed that the CuO and 6%Mn doped-CuO NPs showed a promising ability in removing bacterial contamination and heavy metal toxicity from contaminated water.
