The study on adsorption capacity of metal ions Cr (VI) and Fe (II) was carried out on rubber tree leaves (RTL). The extent of adsorption was evaluated by varying several physico-chemical parameters viz, initial concentration, contact time and pH. The variation in concentration of metal ions after adsorption was analyzed by using atomic absorption spectrophometer (AAS). The results revealed the rubber leaves are valuable adsorbent for the removal of metal ions as the experimental data was followed by Langmuir and Freudlich models.
