As a biosorbent, the plant Sida rhombifolia has been used to remove lead ions from aqueous solutions. The biosorption capacity tests were performed in an equilibrium batch to investigate the effects of contact time (10-120 min), temperature (30-60°C), initial metal ion concentration (10-90 mg/L), agitation speed (50-250 rpm), biomass dosage (50-500 mg), and retention volume on biosorption capacity (25-150 mL). Biosorption was found to be an endothermic process based on the thermodynamic parameters. and impromptu method The pseudo second-order model accurately represented the kinetic data. According to the isotherm studies, the equilibrium data fits better with the Temkin model. The current study's findings suggest that Sida rhombifolia has the potential to be used in the removal of lead from aqueous solutions.
