High concentration of Mn in drinking water is a significant public health problem thereby calling for the need to reduce it to an acceptable level as required by regulatory bodies. This study was motivated by the need to evaluate the potential of low-cost and reusable bio-sorbents: Orange peels (OPs) and sugarcane bagasse (SCB) for the removal of Mn from simulated aqueous solution and water. The solid:liquid ratio of 30 mg:100 mL was applied, and the results revealed that OPs was able to remove 80.95% of Mn(II) at an optimum contact time of 10 min while SCB was able to remove 96.5% of Mn (II) at an optimum contact time of 30 min. The bio-adsorbents were characterized using, Fouriertransform infrared (FTIR) spectroscopy, scanning electron microcopy (SEM) hyphenated to energy-dispersive spectroscopy (EDS), powder X-ray diffraction (PXRD) and thermogravimetric analysis (TGA). From the findings of this study, it follows that the use of OPs and SCB could potentially yield the desired result in Mn removal from water.
