Separation of iron-52 from chromium cyclotron targets on the 2% cross-linked anion-exchange resin AG1-X2 in hydrochloric acid.
Iron-52 can be separated from solutions of chromium cyclotron targets by eluting chromium, copper and radioactive impurities with 9.0M hydrochloric acid from a column containing 1.0 g of AG1-X2 anion-exchange resin. Iron-52 is retained and can then be eluted with 6.0M hydrochloric acid containing 0.05M hydrogen iodide or 0.05M sodium iodide. The separations are sharp and quantitative. Less than 2 microg of chromium will remain with the iron-52, from 2.0 g originally present.
