Abstrakt: AbstractThe interactions of pentavalent Np and Pu with nitrate ligands has been investigated in perchlorate/nitrate media by capillary electrophoresis-inductively coupled plasma mass spectrometry (CE-ICP-MS). The binding constant for the complex PuO2NO3, log10βPuO2NO3°=0.14±0.14, is established for the first time while a new value for NpO2NO3, log10βNpO2NO3°=0.13± 0.14, is proposed. The usual analogy applied between Np(V) and Pu(V) interactions seems to be valid for nitrates.
