Abstract:

A very rapid radiochemical procedure has been developed for antimony and arsenic. A sample is added to a 30 per cent solution of H2SO4 containing a carrier for antimony or arsenic or both. This solution is dropped into a flask containing granular zinc at 100 C. The volatile stibine andor arsine formed is passed through a hot quartz tube and decomposed to the metal, which collects as a metallic mirror on a coller protion of the quartz tube. This metal is dissolved in H2SO4 and assayed. The chemical yield is consistently between 70 and 80. The time required for separation of the metal from the other elements of a fission product solution is about 10 seconds.
