Photochemical Valence Adjustment of Pu and Np in Nitric Acid Solution for Separation and Co-Extraction
Published online by Cambridge University Press: 15 February 2011
Abstract
Photochemical redox reaction tests were corried out where the experimental variables were irradiation rate using a Hg lamp light and molarity of nitric acid containing different reductant reagents such as hydroxylamine(HAN), hydrazine(HDZ) and urea. Based on these tests, we confirmed that the valences of Pu and Np were easily photochemically adjusted to two conditions of Pu(IV,VI)-Np(V) and Pu(IV,VI)-Np(VI), indicating that photochemical valence adjustment for the separation and co-extraction of Pu and Np has excellent potential as an advanced process technology.
