Study on Removal of Lead(II) from Aqueous Solutions Using Sida rhombifolia as Biosorbent

Study on Removal of Lead(II) from Aqueous Solutions Using Sida rhombifolia as Biosorbent 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. #sida #rhombifolia #lead #ii
