LABORATORY INVESTIGATIONS IN SUPPORT OF FLUID BED FLUORIDE VOLATILITY PROCESSES PART VI A. THE ABSORPTION SPECTRUM OF PLUTONIUM HEXAFLUORIDE B. ANALYSIS OF MIXTURES OF PLUTONIUM HEXAFLUORIDE AND URANIUM HEXAFLUORIDE BY. ABSORPTION SPECTROMETRY

摘要

The absorption-spectrum of gaseous, plutonium hexafluoride was determined over the range of wavelengths from 2000 A to 26,000 A, and molar absorbancy indices were calrculated. A test of the spectral method of analysis of pluto-nium hexafluoride in. mixtures of plutonium hexafluoride and uranium hexafluoride was made. The results indicate that plutonium hexafluoride maybe determined in mixtures containing uranium hexafluoride by use of a spectral method although care is required to pretreat the cell windows to avoid reaction with, plutonium hexafluoride.
