The present work illustrates the adsorption of lead from aqueous solutions on Glycosmis mauritiana carbon (GMC) was investigated to assess the possible use as a low cost adsorbent for the removal of lead from waste water. The influence of various factors such as initial concentration, amount of adsorbent, solution pH, particle size of the adsorbent, and temperature on the adsorption capacity has been studied. The percentage removal of lead was observed to decrease with increase in the initial concentration of lead. The adsorption of lead decrease with increase in temperature indicates the exothermic nature of the reaction. The pH value of lead adsorption onto the GMC was found to be 6.0. The results indicated that the activated carbon prepared by sulphuric acid activation (GMC-2) could be used effectively for adsorption of lead (II) ions from aqueous solution. The characterization of the activated carbon prepared was measured to evaluate its high quality.
