The development of economic and efficient processes for the removal of toxic metals from water bodies has become a priority task for environmentalists. Biosorption processes arc tangible alternatives to traditional methodologies, particularly if low metal concentration, large volume and cost arc considered. The present communication reports the unexploited sorption properties of the Saraca indica leaf powder (S1LP) for the removal of Cd(ll) and Ni(II) from aqueous media. Sorption studies using standard practices were carried out in batch experiments as a function of biomass dosage, metal concentration, contact time, particle size and pH. Sorption studies result into the standardization of optimum conditions for the removal of Cd(II) - 92.60% and Ni(II) - 46.20% as follows: biomass dosage (4.0 g), metal concentration (Cd(II) 10 ug/cm3, Ni(II) 10 ug/cm3) and volume of the test solution (200 cm3) at pH 6.5 for Cd(II) and Ni(II). The present study explores for the first time, the efficacy of Saraca indica leaf powder as a novel and environment friendly possibility to remediate heavy metal contaminated water in a cost efficient manner.
