Abstract  

Nondestructive and destructive methods are described for the determination, by neutron activation, of small amounts (more than about 0.001%) of manganese in nickel- and iron-base alloys. In the destructive method, thenoyltrifluoroacetone (TTA) extraction has been applied to the separation of manganese after irradiation.

Abstract  

Extraction-chromatographic separation of uranium from fission products was performed using undiluted tributyl phosphate sorbed on Chromosorb W as a stationary phase, and nitric acid (1: 3) as a mobile phase. Most of the fission products that contributed greatly to the radiation level of the sample passed through the column; this effected considerable decontamination. Uranium retained on the column was quantitatively recovered by elution with water.
