Study of humic acids in various types and kinds of peats at Khantymansi autonomous area - Ygra by NMR 13C spectroscopy

Abstract

This article presents the results of humic acid studies in peat resources of the Khanty-Mansi Autonomous Area -Yugra by NMR 13C spectroscopy. Their differences were revealed in the distribution of carbon atoms along structuralfragments which allowed to diagnose the peculiarities of the drug molecular structure, depending on the botanicalcomposition of the original peat and its degree of decomposition. It was found that humic acids of various peats haveminor differences in the content of Cal. and Carom. The resulting spectroscopic information was used for an in-depthanalysis of the features concerning peat humic acid structure of various origin.
