Abstract
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 γ-ray spectrometry. With the use of ion chromatography, it was found that processes related to the absorption of SO 2−4 and Cl− anions by a solid phase with the release of NO −3 , PO 3−4 , 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 γ-ray spectrometry, it was found that the release of 60Co, 152Eu, and 241Am 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: ∼25% 241Am, ∼3% 152Eu, and ∼0.8% 60Co in the system with added humic acid or 0.8% 152Eu and <0.1% 60Co in the system without the addition of humic acid. The 241Am radionuclide was not determined in the system without the addition of humic acid. An increase in the concentration of WSOC in the experimental system of bottom sediments-Yenisei river water initiated the release of 60Co, 152Eu, and 241Am anthropogenic radionuclides from bottom sediments because of the formation of soluble complexes capable of migration. An increase in the concentration of WSOC had almost no effect on the release of 40K and 137Cs radionuclides.
