In the present study the potential of modified banana peels for the removal of total iron from aqueous system was investigated. Batch mode study was carried out. Isotherm data was generated and fitted in Langmuir and Freundlich equation to explain the phenomenon of adsorption. The adsorption capacities based on Langmuir model (Qm) of the 3 adsorbents were found to be 1.47 for raw banana peel (RP), 0.93 for the grafted peel (GP) and 1.8 mg/g for the Charred peel (CP). The R2 values were 0.99 for raw banana peel (RP), 0.93 for grafted peel (GP) and 0.96 for charred peel (CP). Based on Freundlich model the adsorption capacities (K) were 2.89, 2.78 and 3.95 mg/g for raw peel (RP), grafted peel (GP) and charred peel (CP). The R2 values were found to be 0.96, 0.94 and 0.95 for the raw banana peel (RP) grafted peel (GP) and charred peel (CP) respectively. Our results showed that modified banana peel products can be used as potential adsorbents for removal of iron from aqueous environment
