Mn. Belkova et al., DETERMINATION OF RHENIUM BY RADIOTRACER METHODS OF ANALYSIS, Journal of radioanalytical and nuclear chemistry, 173(1), 1993, pp. 3-8
Radiometric correction and interpolation methods have been worked out
for rhenium determination with extraction of the tetraphenylphosphoniu
m complex into dichloroethane. Liquid scintillation counting was used.
The method allows to determine from 1 to 100 mug of rhenium(VII) in a
nalyzed probe. The relative standard deviation is 0.05-0.09 over the w
hole concentration range.
