Abstract

1,009,236. Purifying radio-isotopes; producing radio-active substances. INSTITUTT FOR ATOMENERGI. Oct. 24, 1962 [Oct. 24, 1961; Feb. 27, 1962], No. 40330/62. Drawings to Specification. Headings G6P and G6R. Trivalent chromium-51 is produced by the neutron irradiation of hexavalent chromium trioxide or potassium chromate in accordance with the reaction The trivalent chromium is produced by the Szilard-Chalmers recoil effect from the target chromium-50. After irradiation, the chromium compound is dissolved and the solution is passed through an anion exchange column, containing a resin, which absorbs the hexavalent chromium and passes the trivalent chromium. The latter has a high specific radio-activity which renders it suitable for medical use as small quantities only may be employed due to its toxic properties. After evaporating the trivalent chromium solution, the pH value is adjusted, using sodium hydroxide, and the trivalent chromium is oxidized to the hexavalent form by hydrogen peroxide. In the case of the potassium chromate target, the solution is passed into a second anion exchange resin where it is adsorbed. It is reduced with ascorbic acid, desorbed and carried to an evaporator in hydrogen chloride solution.
