title: Determination of sulphate and nitrate in plutonium compounds by infrared spectroscopy.
abstract: An infrared spectrophotometric method is described for the determination of sulphate and nitrate in plutonium peroxide and plutonium tetrafluoride. Spectra of the samples in potassium bromide pellets are obtained over the 4000-4680 cm(-1) wavelength region; sulphate is determined from the absorbance of the 1103 cm(-1) absorption band and nitrate from the 1370 cm(-1) band. Data are given on the precision and accuracy for analyses of peroxide and tetrafluoride samples.
