Abstract
The sorption of curium onto various phosphate such as Th-4(PO4)(4)P2O7, ZrP 2O7, Zr2O(PO4)(2), and the fluoroapatite Ca-10(PO4)(6)F-2 has been studied. Laser spectrofluorimetry has been used for monitoring the sorption process es and characterizing the structure of the surface complexes, taking into a ccount the speciation of Cm(III) in solution. The formation of surface comp lexes for thorium and zirconium phosphate and ion exchange for the fluoroap atite have been demonstrated.
