Determination of microimpurities of Ba, Ga, Mg, Mn, Si and Pb in high pure cadmium and tellurium

Description

Chemico-spectral method of determination of (2-6)x10-7 % Ba, Cd, Ga, Mg, Pb and Si, 4x10-8 % Mn in high-purity cadmium and tellurium after extraction-chromatographic isolation of the base was suggested. Graphite powder with CaF2 (5 %) addition serves as collector for microimpurities. The concentrates are analyzed by atomic-emission method in the direct current arc. Relative standard deciations do not exceed 0.1-0.28. The number of the elements determined can be extended
