DETERMINATION OF TRACE CESIUM IN URANYL NITRATE BY FLAME ATOMIC EMISSION SPECTROPHOTOMETRY

    Graphical Abstract
    • Abstract
  • A method is described for the determination of trace cesium in uranyl nitrateby flame atomic emission spectrophotometry.The ionization interferences can besuppressed by the addition of potassium.The interferences of coexisting elementsare studied.Concentration ranges from 0.5 to 5 ppm.The recovery and coefficientof variation are 97—100％ and 3％ respectively.
