The aim of the work is to explore the properties and composition of humic acids isolated from raised bog peat prospective for industrial use, and the factors that influence their properties and composition. The tasks of the thesis: 1. to collect peat samples from different bogs, study their properties, humification of peat and factors influencing it; 2. to explore the extraction process of humic acids from peat using different high-intensity extraction methods; 3. to characterise the properties of peat humic acids and evaluate the influence of the peat properties on the properties and composition of humic acids.
