Abstract

The present study investigates the possibility of removing lead ions from aqueous solution in batch process by the adsorption onto low cost biosorbent sunflower husks. The influences of different adsorption parameters such as pH, contact time, adsorbent dosage and metal concentration have been studied. The best removal efficiency (94.5%) achieved when pH 5, 120 min contact time, 1 g/100 ml dosage and 10 mg/l initial metal concentration at room temperature. The equilibrium sorption data was fitted to the Langmuir and Freundlich isotherm models. The Freundlich model represents the equilibrium data better than the Langmuir model. Result showed that the sunflower husk was found to be low-cost adsorbent for the removal of Pb+2 ions from wastewater.
