The goal of the current investigation was to identify the ideal conditions for eliminating Pb(II) at a concentration of 100 mg/L from wastewater utilizing cotton-derived plant urease enzyme. According to the findings, the urease enzyme can remove Pb(II) up to 97% more effectively than the control at the same concentration after 3 hours of contact time and a 1:1 (v : v) ratio at pH 4.0. The AA test, “Fourier transform infrared spectroscopy” (FTIR), and “scanning electron microscopy” (SEM) were used to approve the results.
