Hydroxyapatite HA was prepared from catfish bones identified as catfish HA CFHA using mechanical and chemical treatment methods CFHA was characterized by xray diffraction XRD and scanning electron microscope SEM techniques to confirm the presence of HA The ability of CFHA to remove uranium UVI from aqueous phase was investigated using both batch and column experiments Adsorption experiments in batch experiments were carried by varying pH preparation temperature and particle size The data shows that the maximum adsorption occurred between pH 55 and 7 The adsorption of UVI on CFHA was greater at 300 °C than at 100 °C Batch data shows that the smallest particles with maximum surface area exhibited significant UVI removal efficiency Column experiments were conducted using the smallest CFHA particles at different flow rates and breakthrough profiles were obtained The scalability of the UVI removal process was tested by comparing the performances of columns packed with different CFHA The results indicated that the reaction scales to the mass concentration of the reactants CFHA and UVI We also found that at pH 7 the CFHA packed in the column has the potential to remove about 39 mg of UVI per gram Our study shows that CFHA may be used in permeable reactive barriers for remediating UVIcontaminated groundwater plumes
