Аннотация: The effect of humic acid on absorption-release processes in the bottom sediments-Yenisei river water system was studied by dual-column ion chromatography and gamma-ray spectrometry. With the use of ion chromatography, it was found that processes related to the absorption of SO42- and Cl- anions by a solid phase with the release of NO3-, PO43-, and F- to a liquid phase competed in the test systems as the concentration of water-soluble organic carbon (WSOC) was increased. Only the test anions were released in the systems without the introduction of an additional amount of WSOC as humic acid. With the use of gamma-ray spectrometry, it was found that the release of Co-60, Eu-152, and Am-241 radionuclides to the liquid phase in the systems with added humic acid began much earlier than in the system without the addition of humic acid. In this case, the amount of released radionuclides was greater than the amount of radioisotopes released in the system without the addition of humic acid: similar to 25% Am-241, similar to 3% Eu-152, and similar to 0.8% Co-60 in the system with added humic acid or 0.8% Eu-152 and
