Влияние ботанического состава и степени разложения торфа на элементный состав гуминовых кислот

Abstract

The subject of the study was the samples of peat are most typical for the middle taiga zone of the West Siberian plain. The purpose of the study is to identify the relationship between the botanical species of the peat, degree of decomposition and chemical composition of the resulting humic acids. The influence of botanical species and decomposition degree of peat on the elemental composition and the practical yield of humic acids were studied. It is shown that the mechanochemical method of obtaining of humic acids can be applied to all kinds of peats of Western Siberia, regardless of botanical species and degree of decomposition. The yield of humic acids from peat directly correlated with the degree of peat decomposition. The use of cavitation of peat for preparation of humic acids eliminates differences in the elemental composition of humic acids obtained from various species of peat raw materials with different degree of decomposition. For the industrial production of humic acids proposed mechanochemical method allows the use of peat, produced by any method, including excavation.
