It is required to separate uranium and protactinium in the determination of highly enriched uranium age.Distribution coefficients of uranium and protactinium were studied with the concentration of hydrochloric acid,hydrofluoric acid,and so on using nature uranium and ~(233)Pa as tracers.The method of separating protactinium and uranium using the TEVA chromatographic method was developed.The radiochemical recovery of protactinium is 99%.The decontamination factor for protactinium is 5.4×10~3.The chemical rec...
