Kinetics of Novel Extraction Systems Used in the Partitioning of Nuclear Waste

Abstract

Both 2,6-di(5,6-dipropyl-1,2,4-triazin-3-yl)pyridine (n-Pr-BTP), and a synergistic mixture of di(chlorophenyl)dithiophosphinic acid and tri-n-octyl phoshine oxide, are able to selectively extract trivalent actinides over lanthanides from 0.5-1 M nitric acid. We focused on clearly identifying the extraction regime (chemical or diffusional) of these… (More)
