Methods are given for the isolation of Tc/sup 99m/ from fission products by coprecipitation and anion exchange. In the coprecipitation method, the precipitate was in the molybdate (Mo/sup 99/) form of lead, calcium, silver, etc., for the various procedures. Of these, the yield of Tc/sup 99m/ from PbMoO/ sub 4/ was the best, while silver was next with 50 to 60% yield. In the anion exchange techniques, technetium was not eluted with 10% NaOH but was eluted with 3 to 7 N HNO/sub 3/. The process was very slow and unpredictable for other acids and for dilute HNO/sub 3/. The yield was 40 to 45% in Tc/sup 99m/ at 95% purity for 7.5 N HNO/sub 3/. (B.O.G.)
