The determination of samarium, europium, gadolinium and dysprosium in uranium products by direct-current plasma emission spectrometry.
Samarium, europium, gadolinium and dysprosium were separated from uranium-containing materials by means of solvent extraction with Alamine 336, followed by cation-exchange. The elements were determined in the sub-ppm range by means of direct-current plasma atomic-emission spectrometry.
