The roles of selected organic compounds on K/sub d/ (distribution coefficients) values of radionuclides in laboratory sediment-water systems was evaluated. The radionuclides /sup 57/Co, /sup 106/Ru, /sup 137/Cs, and /sup 241/Am were used as tracers in the experiments. Five organic compounds: 1)1-nitroso-2-naphthol; 2)1,10-phenanthroline; 3)acetic acid; 4)salicylic acid; and 5)EDTA were evaluated for their effects on the distribution coefficients of the four radionuclides. The results of the study confirmed that organic compounds can affect sediment-water distribution coefficients of radionuclides, however, the magnitudes and directions of these K/sub d/ effects are functions of both the physico-chemical properties of the radionuclide and the specific interactions of the radionuclide and organic compound within a given sediment-water system. The results emphasize the complex variety of interacting factors that can effect sediment-water distributions of radionuclides. Therefore, it is necessary in any adsorption study to characterize, as fully as possible, the chemical parameters of water and sediment that can contribute to the eventual results in any given system.
