THE STUDY OF THE MOLECULAR COMPOSITION OF HUMIC SUBSTANCES OF COAL AND PEAT BY HIGH RESOLUTION MASS SPECTROMETRY WITH OPTIMAL ELECTROSPRAY CONDITIONS
Significant progress in the understanding of molecular diversity in the structure of organic matter in nature has been achieved recently through the use of high resolution mass spectrometry, namely, Fourier transform ion cyclotron resonance mass spectrometry (FTI- CR MS) in combination with electrospray ionization. Obtaining reliable information about the molecular composition of the organic matter of fossil coal and peat is essential to meet the new challenges facing the coal industry aimed at search of new technologies and methods for processing and method for non-fuel use of coal, in particular, with a view to their processing in high-tech chemicals, new materials and polymers. The optimal conditions were found for high resolution mass spectrometry analysis of humic substances isolated from solid fuels - coal and peat. The study of the molecular space of humic substances from peat and coal in the selected optimal conditions allowed us to record the presence of poorly ionized carbohydrate and saturated hydrocarbons.
