Determination of organic impurities in cobalt production solutions using gas chromatography-mass spectrometry

Gas chromatography-mass spectrometry has been used for the analysis of cobalt production solutions by JSC “Kola MMC”. The presence of some new organic impurities in the circulating extractant was established and their influence on the physicochemical properties of the extractant has been determined. The paper considers reasons for the appearance of esters and chlorine derivatives impurities in solutions.
