OSTI ID:4321949
A method is presented for the determination of 14 rare earth elements in high-purity uranium compounds by emission spectrography. The rare earth elements are chromatographically separated from uranium by using alumina-hydrofluoric acid. Lanthanum is used both as collector and internal standard. The technique of excitation involves a total consumption of the sample in a 17-ampere direct current arc. The range of determination is about 0.005 to 0.5 mu g/g uranium. The coefficient of variation for Pr, Ho, Dy, Er, Tm, Lu, Gd, and Tb amounts to 10%. (INIS)
