Autor: Jean Aupiais, Violaine Philippini, Benoit Brunel, Mickaël Mendes

Publikováno v: Radiochimica Acta. 103:27-37

Complexation of various actinides (U(VI), Np(V), Pu(V), Am(III)) by oxalato ligand was studied by capillary electrophoresis (ICPMS detection) in 0.1 mol L –1 NaClO4 ionic strength solutions at various temperatures (15, 25, 35, 45 and 55 ℃). For e

Evidence of Different Stoichiometries for the Limiting Carbonate Complexes across the Lanthanide(III) Series

Autor: Violaine Philippini, T. Vercouter, Pierre Vitorge

Publikováno v: Journal of Solution Chemistry. 39:747-769

The stoichiometries of limiting carbonate complexes of lanthanide(III) ions were investigated by solubility measurements of hydrated NaLn(CO3)2 solid compounds (Ln = La, Nd, Eu and Dy) at room temperature in aqueous solutions of high ionic strength (
