Abstract

Since the industrial revolution, water pollution, including wastewater, has attracted researchers’ attention. An effective and environmentally friendly method for the green synthesis of copper oxide nanoparticles (CuO NPs) with aqueous extracts of Aloe vera and Gundelia tournefortii as an adsorbent for heavy metals has been developed. The formulated NPs were analyzed by X-ray diffraction, Fourier-transform infrared spectroscopy, field-emission scanning electron micros-copy, and energy-dispersive X-ray spectroscopy techniques. Absorption experiments were performed on aqueous solutions at various concentrations and pH. The elimination rate of Pb2+ was investigated by an atomic absorption system. Different conditions for the removal of lead ions were considered, and the green-produced CuO NPs presented high photocatalytic activity for removing lead ions from wastewater. According to the results, the optimum condition for eliminating heavy cation Pb2+ with more than 99% efficiency was achieved at a concentration of 200 mg/L, pH = 7.5, and 0.008 g of CuO NPs. According to experiments, by increasing the amount of NPs, the percentage of lead ions has increased owing to the high available absorption sites against the fixed amount of metal ions. © 2022 Desalination Publications.
