1) By irradiation of a tin target (antimony content, less than 8×10−4%) with 15 MeV. protons (120 μ amp. hr.), about 1 mc. of 120Sb was produced, with a specific activity more than 30 μc. per μg of antimony.2) The radioactive antimony was either separated by extraction with amylacetate from more than 6 nhydrochloric acid containing tin(IV) or by cation exchange in a 0.4% tartaric acid solution of pH 0.6 to 1.6 containing tin-(II).3) 120Sb is electrolytically deposited on an evaporated film of silver or copper from a 1 to 3nhydrochloric acid solution containing 1% hydroxylamine hydrochloride with a yield of 70% within 3 hr.4) Care should be taken to avoid hydro-lytic aging of antimony in diluted hydrochloric acid, which vitiates the extraction, the ion exchange, and the electrolysis. |
