A STUDY OF THE ABILITY OF CuO AND 8% DOPED CuO NANOPARTICLES

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 oxide (CuO) and 8% manganese-doped copper oxide (8%Mn doped-CuO) nanoparticles in removing both bacterial and heavy metal contaminants from water. The contaminants of interest are Staphylococcus aureus and cadmium (Cd) ions. The nanoparticles 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 nanoparticles in removing cadmium from contaminated water was carried out using adsorption study. Also, the effectiveness of the nanoparticles synthesized, was carried out using bacteriological analysis and turbidimetry. The results obtained revealed that the synthesized nanoparticles were efficient in removing Staphylococcus aureus and cadmium ions from contaminated water. However, it was observed that 8%Mn-doped CuO nanoparticle was more efficient in removing Staphylococcus aureus and 8%Mn doped-CuO nanoparticle was more efficient in removing cadmium ions from contaminated water. On the overall, it was observed that the CuO and 8%Mn doped-CuO nanoparticles showed a promising ability in removing bacterial contamination and heavy metal toxicity from contaminated water.
