|Title:||Modelling of distribution coefficients of nitrous acid in 15-30 vol.% TBP/n-dodecane-nitric acid system|
Koganti, S B
|Abstract:||During partitioning of uranium and plutonium, nitrous acid re-oxidises Pu(III) to Pu(IV). Therefore a large excess of U(IV) is required. Since the scavenger reagent ‘‘hydrazine’’ is not extracted into the organic phase, even a small amount of extracted nitrous acid will cause cyclic reactions in the organic phase. In this scenario, study of the distribution behaviour of nitrous acid is important. In this paper, a model, based on extraction mechanism, is reported and compared with the model reported in the literature. The model reported here is considered more reliable than the model available in the literature.|
