Аннотация:The influence of major constituents of multicomponent glass samples (Nb, Ge, Al, Li, Ba, Na) and some organic solvents and their mixtures on AA determination of trace amounts of copper and cobalt has been examined. The extraction-chromatorgraphic distribution of of major and minor components of the samplee in a tri-n-octylamine (teflon) - HBr system has been studied. The possibility has been shown of AA determination of Cu and Co after their extraction-chromatographic separation from the matrix. The detection limits are 2x10-6 and 3x10-6% respectively, the relative standard deviation is not greater than 0.1.
