Abstract

Abstract: The efficacy of using Musasapientum (banana) peels was tested for the removal of Cd and Pbusing batch experiments from textile industrial effluent. Standard spectophotometric techniques using AAS were adopted to assess the concentrations of the heavy metals before and after treatment of effluent with the biosorbent (banana peels). Metal sorption increased proportionally with the equilibrium metal concentration. The adsorption capacity of banana peels on the metal ions was of the order: Cd >Pb, with percentage removal of metal ions as 99.93% for Cd and 99.64% for Pb. Biosorption equilibrium isotherms were plotted for metal uptake capacity (q) against residual metal concentration (Cf) in the sample and mathematically expressed by Langmuir and Freundlich models. The values of separation factor were between zero and one, indicating favorable sorption for the two metals (Cd and Pb) on the biosorbent. Peels of M. sapientum showed comparable biosorption capacity for Cadmium and Lead with other types of biosorbent materials found in literature and are cost effective, economical and eco-friendly in removal of these heavy metals from textile effluent sample.
