Elemental composition and structural peculiarities of humic acids in bog waters of taiga zone

摘要

Results of a complex studying the preparations of humic acids from bog waters by methods of IR spectroscopy, nuclear magnetic resonance and electronic paramagnetic resonance have been considered in the paper. Properties of humic acids are evaluated according to the elemental composition. Commonality and character of varying the composition of humic acids under forest oligotrophic and mesotrophic bogs are discussed hereaswell. The opinion about probable mechanisms of humic acid synthesis in bogs of different genesis is suggested.
