Actinide speciation using synchrotron radiation

The following example focuses on the thermal diffusion mechanisms of trivalent metal ions in a solid matrix, hydroxyapatite. Trivalent europium has been studied here as an analog of americium (III). The apatite used in this study has a monoclinic structure (a = b = 9.46 Å, c = 6.88 Å) and its exact formulation is : Ca _9.1 Na _0.50 (PO ₄ ) _4.7 (HPO ₄ ) _...
