The aim of this study was focused on the investigation of supramolecular structure of humic acids (HA). This issue was studied on a number of HA samples which differed in source matrix (lignite, leonardite, biochar, soil, peat and compost). For these purposes, methods of size exclusion chromatography coupled with UV-VIS, MALS (multiangle light scattering) and dRi (differential refractometry), as well as dynamic and electrophoretic light scattering and UV-VIS spectrometry were used. In order to better understand the formation of the supramolecular structure of HA, the ways of its stabilization and how it was influenced by the change in pH, individual HA samples were studied in three pH-varying mediums (3,5; 7 and 12).
