Potential monitoring for reducing power of solution containing HNO3-Al(NO3)3-UO2(NO3)2-Npsup(4+,5+)-Pusup(3+,4+)-FeSA
[en] The relationship between redox potential of a solution containing 1.5M HNO3-1.5M Al(NO3)3-xM FeSA and Fe3+/Fe2+ ratio has been studied. The formal potential of 777 m V vs SHE of Fe3+-Fe2+ couple in a given solution was obtained. Observed anomalous potential jump of Fe3+-Fe2+ couple depends on Fe3+/Fe2+ ratio, SA concentration and surface condition of platinum electrode. The potential measurement of radioactive solution is a promising method for estimation of Fe3+/Fe2+ ratio and Np, Pu valency change in the solution. (author)
