Chemical co-precipitation synthesized novel and green cobalt-oxide nanoparticles (Co3 O4 -NPs) utilizing cobalt nitrate as cobalt precursors. FTIR, Raman, scanning electron microscopy, UV visible, X-ray powder diffraction, and BET was used to analyze the surface characteristics, composition, and morphology, of the NPs. These green Co3 O4 -NPs were employed to remove Pb ions from simulated wastewater solutions at various pH, adsorbate, temperature, and dose concentrations. At dose 0.2 gL-1 , pH 5.0, 20 mg/L, 25 °C of temperature, and 30 min for equilibrium, nearly 99...
