- The plant Sida rhombifolia has been used to remove lead ions from aqueous solution as a biosorbent. The biosorption ability tests were carried out 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 the biosorption capacity (25-150 mL). The thermodynamic parameters revealed that biosorption was an endothermic and spontaneous method. The kinetic data were well represented by the pseudo second-order model. The equilibrium data suits better with the Temkin model, according to the isotherm studies. The results of the present investigation indicate that the Sida rhombifolia has a potential for use in removing lead from aqueous solutions.
