Abstract Adsorption of Hg and Pb from aqueous phase on the bio-adsorbent prepared from the roots of Mangifera indica was studied, under various conditions like pH, contact time, initial metal ion concentration, doses of adsorbent and temperature. The bio-adsorbent had good adsorption capacity for both of the heavy metals at pH 5 and 6, with optimum contact time of about 75 minutes at low concentrations. The extent of adsorption was found to be inversely proportional to the temperature and increased with the doses of bioadsorbent, which was found to be efficient in adsorption of toxic metal ions of Hg and Pb from aqueous medium.
