Uranyl nitrate, UO 2 (NO 3 ) 2 , was irradiated with a 25 MeV/nucleon 40 Ar ion beam, and the target material removed by means of solvent extraction. A radioactive multitracer solution containing 47 elements and 83 nuclides free from carriers was thereby prepared. The multitracer solution was used in an adsorption study of 47 elements on alumina and bentonite. The distribution coefficients (K d ) of the 47 elements were simultaneously determined and correlated with the electron binding energy (I z ), and explained by the thermodynamic model for adsorption of James and Healy (1972).
