The current study aims to efficiently use nanomaterials as an environmental protection tool to maintain a safe environment Safe, maintains human health, and supports community well-being by improving chemical water quality. In practice, carbon nanotubes (CNTs), as chemical sorbents, have been evaluated for their ability to remove lead and copper ions from water. Adsorbent concentrations, adsorbent dosage, and contact time were also evaluated. Extent of removal (%) of lead. It was found that copper is inversely related to the concentration of the elemental metal; It decreases when the metal concentration increases from 50 to 100 mg/L. CNT was more effective in removing lead than copper, with better removal efficiencies of both ions (50 and 100 mg/L) reaching more than 80%. Under optimal conditions, lead and copper concentrations at 50 mg/L were reduced to 1.1 and 1.8 mg/L (pH 7, contact time 180 min, and biosorbent dose 50 mg). At both doses (50 and 100 mg), the amount of both lead and copper adsorbed onto the CNT was much lower in the competitive adsorption (binary solution) than in the single ion adsorption. Regarding the dynamic behavior of carbon nanotubes, the zero-order model It was used to describe the kinetic adsorption process of lead and copper on CNT. Low dose (50 mg) was associated. Significantly higher levels of net profit per liter of water and benefit-cost ratio (BCR), as well as significantly lower costs. Heavy metal removal efficiency has been found to be positively related to CNT dosage. Therefore, CNT can be considered an efficient and cost-effective nanosorbent material, capable of removing water pollutants relatively quickly at low dose and low cost.
