Abstract
Traces of lanthanides can be separated effectively from major lanthanide oxides by liquid chromatography on a column of Separon SGX-C-18 silica gel modified by sorption of ammonium dodecylsulphate, and determined by flame - or inductively coupled plasma-atomic emission spectrometry. Spectral interferences from the major component at concentration ratios up to 10(4)-10(6) can be eliminated by isocratic or stepwise pH-gradient elution with ammonium 2-hydroxyisobutyrate. Methods of determining europium, ytterbium and holmium in yttrium, lanthanum and lutetium oxides are described. The flame method is shown to have some advantages.
