The extraction part of the technological scheme for radiochemical separation of components of irradiated vanadium-chromium-titanium (V-Cr-Ti) alloy and for their purification from metallic activation products was tested on the whole using activated alloy specimens. It was shown that the replacement of the acid re-extraction of vanadium with a peroxide re-extraction and of the acid re-extraction of chromium with an alkaline re-extraction substantially improves the characteristics of the extraction reprocessing of the activated V-Cr-Ti alloy. In particular, the durations of the vanadium and chromium re-extractions were shortened by about an order of magnitude, the outputs of these alloy components increased, vanadium purification from rare-earth metals became twice as great, and chromium decontamination from cobalt increased by two orders of magnitude.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
