In this study, agro-waste material were used as adsorbent for removal of lead, zinc, cadmium and nickel from aqueous solution. This work aims to optimize conditions for preparation of this materials to obtain maximum metals adsorption capacity. optimal conditions were determined in terms of removal of metals efficiency or energy consumption. The results indicate that maximum adsorption takes place at pH 7-8, contact time of 2 hours, adsorbent dose of 1.8 g, initial concentration of 60mg/L and at a temperature of 340 K. Peanut husk is a good adsorbent for the xenobiotic and non-xenobiotic heavy metal. The trend of uptake for peanut husk is in the order of Zn (II)> Ni (II)> Pb (II)> Cd (II).
