A RAPID RADIOCHEMICAL PROCEDURE FOR TIN
Abstract
A very rapid radiochemical procedure has been developed for the isolation of radioisotopes of tin from their fission-product isobars. An ir radiated uranium solution containing tin and antimony carriers is added to a solution of sodium borohydride. The volatile stannane (SnH4) formed is decomposed in a hot quartz tube to the metal, which is collected on a cold surface. Stibine (SbH3), which is also formed under these conditions, is removed by absorbtion on an 'ASCARITE' column. The tin chemical yield ranges between 15% for an Sb decontamination factor of 20,000 to 60% for an Sb decontamination factor of 1,000. The time required for separation of the tin metal from the other fission product elements is about 10 sec. Decontamination factors of other Sn descendents are: I 70,000, and Te > 20,000. Arsenic is also volatilized as the hydride; however, it is not necessary to elimi nate it in this work for the determination of the Sn fission yield.
