Combined transuranic-strontium extraction process
Abstract
The transuranic (TRU) elements neptunium, plutonium and amercium can be separated together with strontium from nitric acid waste solutions in a single process. An extractant solution of a crown ether and an alkyl(phenyl)-N.N-dialkylcarbanylmethylphosphine oxide in an appropriate diluent will extract the TRU`s to gather with strontium, uranium and technetium. The TRU`s and the strontium can then be selectively stripped from the extractant for disposal.
