The article presents data on the elemental and functional composition of humic acids, their molecular weight characteristics, physical, chemical and acid-base properties. The sorption properties of humic acids towards Cd2+ and Pb2+ are studied. The relationship between the polyelectrolyte nature of humic acids and their sorption capacity is revealed.
