Abstract Abstract. This study deals with the understanding of the cadmium uptake mechanism by synthetic stoechiometric hydroxyapatite (Ca10(PO4)6(OH)2) in aqueous solution. Three parameters were studied: the powder specific surface (SBET), the initial Cd2+ concentration ([Cd2+]o) and the time of the sorption experiments (tcontact). We have find that the quantity of cadmium immobilized by the hydroxyapatite is mainly controlled by the sample specific surface area. The analyses after the reactions of immobilization, indicate the presence of cadmium adsorbed to the surface of crystallites and a solid solution of the Ca(10-x)Cdx(PO4)6(OH)2 type (with x = 1 + 3y and 1 < x < 4).
