Abstract
The interaction of the uranyl group UO22+ in aqueous solutions with hydroxy lapatite and fluoroapatite was studied by X-ray photoelectron spectroscopy. The apatite samples under study were found to contain CO32- groups. The re action of uranyl nitrate with hydroxylapatite in aqueous solutions does not lend to U(IV)-containing compounds but forms U(VI)-containing uranyl compo unds with equatorial hydroxyl or carbonate groups partly replaced by fluori ne in the uranyl compounds in the case of fluoroapatite.. The interaction o f the uranyl group with fluoroapatite in aqueous solutions is much more eff ective than the interaction with hydroxylapatite.
