Abstract

A method is proposed for the simultaneous determination of the matrix element Co and alloying elements (Cr, Ni, W, Si, Mn, Fe, Mo, Ti, Ta, V) in cobalt alloys for various purposes by inductively coupled plasma atomic emission spectrometry with preliminary microwave sample opening. A scheme for dissolving samples of cobalt alloys of different grades in a microwave decomposition system in 2 stages is described, which ensures the complete transition of the elements into solution. Analytical lines of elements free from significant spectral influences are selected. The metrological characteristics of the method are evaluated based on the results of the analysis of reference materials.
