GRAVIMETRIC DETERMINATION OF URANIUM WITH THE USE OF CUPFERRON FOR ITS SEPARATION (in Russian)
The method is based on the separation of admixtures with cupferron and precipitation of tetravalant uranium with the same reagent after reduction with sodium hyposulfite. The method has been tasted on pure uranium, artificial mixtures with accompanying uranium admixtures, as well as on ores and headings with various concentrations of uranium. The method can be used for the precision analysis of ores and headings containing more than 5 % of uranium in plant laboratories. One determination takes 4 to 5 hrs. Four samples can be analyzed simultaneously. The mean quadratic error of determination is estimated to be plus or minus O.3% relative fur samples containing 50% and plus or minus 1.2% for samples containing 5 to 10% of uranium. (tr-auth)
