Abstract— This study was carried out to investigate the use of two novel agricultural by-products namely: oil-free Moringa oleifera cake and sweet potatoes peels for the removal of Cr (VI) ion from a typical tannery wastewater. Biosorbents were produced from these two agricultural by-products, surfaces of these biosorbents were modified using 1N NaOH and 6N HCl, subsequently the modified and unmodified biosorbents were used for the removal of Cr (VI) ion from tannery wastewater using the batch process technique. Results obtained showed that the acid modified biosorbents gave the best results with removal efficiencies of 59 and 74% for oil-free Moringa oleifera cake and sweet potatoes peels respectively at pH of 7.0. Kinetics investigation revealed that both agricultural by-products followed the pseudo-first order kinetics. From the results obtained, oil-free Moringa oleifera cake and sweet potatoes peels were effective biosorbent for the removal of Cr (VI) ion from tannery waste water.

Index Terms— Tannery wastewater, chromium (VI) ions, batch process, surface modification.
