摘要

The biological activity of humic preparations in the form of sodium and potassium humates was investigated depending on the structural group parameters of humic acids (HAs): the degree of aromaticity (f(a)), a hydrophilic-hydrophobic parameter (f(hh)), and a parameter reflecting the ratio between aromatic and aliphatic fragments in the organic matter of HAs (f(ar/al)). Native and modified HAs isolated from peat and brown coals of Russia and Mongolia, the composition of which was characterized using proximate and ultimate analysis and C-13 NMR (CP MAS) spectroscopy, were used as preparations. It was established that modification by destructive alkylation and the subsequent bitumen removal changed the structural-group composition of HAs, increased the degree of aromaticity, and led to an increase in their biological activity.
