This work deals with the study of the removal of lead from aqueous solution using low cost adsorbent obtained from the leaves of centella asiatica . Effect of pH, adsorbent dose, dye concentration, contact time and temperature on the removal of the metal ions was investigated. Equilibrium data were analyzed using Langmuir and Frendlich isotherm models. The maximum removal was obtained for the adsorbent dose of 100mg at 10mg/l metal concentration at pH 5 and agitation speed of 120rpm. The result shows that Centella asiatica leaf could be employed as an effective low cost adsorbent for the removal of Lead.
