DETERMINATION OF RHENIUM BY NEUTRON ACTIVATION
1966
Abstract A neutron activation method is proposed for the determination of rhenium in rocks and ores. After the irradiation, the radiochemical separation consists of a one-step anion exchange; β-activities of radiochemically pure 188 Re or 186 Re are counted. The chemical yield averaged 75% and there was a considerable saving of time in the radiochemical work. Results are quoted for the rhenium contents of the standard rock W-1, several molybdenites and pyrolusites.
