Description

The 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, log10β PuO2NO3 = 0.14 ± 0.14, is established for the first time while a new value for NpO2NO3, log10β NpO2NO3 = 0.13 ± 0.14, is proposed. The usual analogy applied between Np(V) and Pu(V) interactions seems to be valid for nitrates. (orig.)
