The reported study highlights unexplored efficacy of modified Ficus religiosa Leaf Powder (FRLP) as an effective biomaterial for the abatement of chromium (VI) from aqueous system. Considering the metal-acid interaction responsible for binding of metal species, enrichment of amino group has been carried out using synthetic modifications onto F. religiosa Leaf Powder (FRLP) which results into the increase in percentage sorption efficiency and stability in terms of regeneration cycles. Desorption studies showed that the ease of metal ion recovery from metal-loaded biomass by the different eluents is of the order nitric acid [0.05M] > citric acid [0.5 M] > sodium hydroxide [0.05M] > distilled water. This easily abundant agricultural waste FRLP, as a biosorbent has potential for a low technological pre-treatment step, prior to economically non-viable high-tech chemical treatments for the removal of Cr (VI) from water bodies.


Key words: Biomaterial, chromium, Ficus religiosa, biosorption, amino acid-Cr (VI) interaction, pretreatment.
