Humic acids have an important role in the soils. When specific structures of which little is known, are studied, one should use the latest analitycal methods. So far the method of fractionation by electrophoretic mobility has not been very popular in the research studies on humic substances. However, it seems that it is possible to study humification processes and subtle changes in the structure of the material investigated using capillary electrophoresis. On the basis of our experience, some soils representing various types were selected as study material. Electrophoretic separation (by means of buffer solutions with various pH-values) was carried out for the humic acids extracted from the soils selected. The results obtained allowed for the determination of differences in the humic acids structures due to their origin.
