Abstract

In this present work, the leaves of Kadam (Neolamarckia cadamba) were used as adsorbent for the removal of Methylene blue dye from aqueous solution. The adsorption characteristics of the dye on Kadam leaf powder was evaluated as function of pH, initial concentration of adsorbate, contact time and adsorbent dose. The effective adsorption was found to be in the conditions of pH 4, initial adsorbate concentration of 10 mg/L, contact time of 30 mins and adsorbent dose of 0.4 g at 120 rpm agitation speed at room temperature. The results reveal that maximum percentage adsorption of dye onto Kadam leaf powder was 95.1.
