“…Ion exchange finds many applications as a means of concentrating impurities prior to spectral analysis. Separation of rare earths by ion exchange was reported by Smith and Smith (282), by Kallmann, Oberthin, and Hibbits (146), and by Carter and Dean (57). Walkden and Heathfield (318) describe the application of ion exchange to the concentration of impurities from uranium.…”

ABS'mACTA spectrochemical analysis of uranium for samarium and europium, without prior separation is presented. The method is based on excitation of uranium in the chloride form with potassium chloride as buffer and by use of 4A DC-arc excitation. Under these conditions it is possible to overcome the difficulties arising from the complex spectrum and heavy background of uranium. The limits of detection for europium and samarium are 5 and 20 ppm, respectively: the coefficient of variation for Eu and Sm Is about 25" for a single determination. The Visually established limIt of detection for gadolinium and dysprosium Is 50 ppm.
