The paper presents a multi-element analysis of europium, yttrium and lanthanum compounds by atomic emission spectrometry with inductively coupled plasma (ICP-AES). The plasma power was optimized, the choice of analytical lines of the impurities to be determined and the concentration of matrix element were substantiated. The method allows to determine up to 40 trace elements with the limits of detection (LODs) ranging from 10 –6 to 10 –3 wt %.
