Abstract
Adsorption of Gd3+ and Mn2+ into hydroxyapatite (HAP (Ca5(PO4)3(OH)2)) was studied by ESR, ion chromatography and ICP-AES to investigate the U-uptake model. HAP absorbed Gd3+ via a cation exchange reaction and resulted in a signal width of 240Â mT. The growth of the thermally stable Gd3+ signal in HAP was also fitted by saturation and diffusion equations. The ESR signals of Gd3+ and Mn2+ were observed overlapping the CO2â signals, however, the dose-response curves of the CO2â signal were similar to that of control HAP.
