Solvent Extraction Method for the Radiochemical Determination of Zinc
This method for the determination of radioactive zinc in fission-product mixtures is based on strong base scavenging of basic medium insoluble ions with amphoteric zinc remaining in solution, followed by solvent extraction of the diethyldithiocarbamate complex into ethyl acetate. Zinc was removed from the organic phase by stripping with dilute hydrochloric acid. The yield determination was based on an EDTA titration with Eriochrome Black T indicator. Counting was done in a well-type NaI(TI) scintillation crystal. The method was evaluated by measuring the fission yield of Zn72 in a thermal neutron- irradiated sample of U235. A value of 2.6 x 10-5% is reported.
