Neptunium(V) ions are unstable in acid media, which limits their extraction on chromatographic resins We developed a novel analytical method to measure Np by either alpha-spectrometry or inductively coupled plasma mass spectrometry (ICP-MS) after extraction chromatography as Np(VI). We investigated the reactivity of various oxidizing reagents, and determined the retention capacity of Np(IV, V. and VI) on various extraction chromatographic supports. A simple method using two UTEVA resins was used to rapidly detect Np in soil and sediment samples (C) 2010 Elsevier Ltd All rights reserved
