| Abstract: | A thermal neutron activation method for the determination of rhenium in molybdenites is described. The rhenium is separated from the matrix after irradiation by pyridine extraction from 4 N sodium hydroxide solution; γ- and β-spectrometry are applicable. For a neutron flux of 4 · 1011 n/cm2.sec, an irradiation of 2 h and a sample of ca. 50 mg, β-counting allows determinations in the p.p.b. range. |
