FIELD: nuclear technology.
SUBSTANCE: invention relates to nuclear technology, to analytical support of the closed fuel cycle technology, in particular, to analysis of the chemical purity of compounds of plutonium, neptunium, americium and curium. The method for joint determination of the mass content of Al, B, Fe, Cr, Pb, Mo, Ni, Ti, Ca, Cu, Na, Si in compounds of plutonium, neptunium, americium and curium consists in direct analysis of nitric acid solutions by the method for atomic emission spectroscopy with an arc source of spectra. The concentration of americium or curium in the analysed samples is therein not greater than 4 g/dm3, and the concentration of plutonium or neptunium is not greater than 2 g/dm3.
EFFECT: possibility of determining the mass content of cationic impurity elements in individual compounds of actinides of various forms in a short time for 2 to 3 hours is provided.
