Abstract

The interaction of the uranyl group UO 2 2+ in aqueous solutions with hydroxylapatite and fluoroapatite was studied by X-ray photoelectron spectroscopy. The apatite samples under study were found to contain CO 2 2+ groups. The reaction of uranyl nitrate with hydroxylapatite in aqueous solutions does not lead to U(IV)-containing compounds but forms U(VI)-containing uranyl compounds with equatorial hydroxyl or carbonate groups partly replaced by fluorine in the uranyl compounds in the case of fluoroapatite. The interaction of the uranyl group with fluoroapatite in aqueous solutions is much more effective than the interaction with hydroxylapatite.
