[Adsorption behavior and distribution coefficient of 137Cs and 85Sr on sand (author's transl)]. 1980

T Yamamoto, and S Takebe, and Y Wadachi

The adsorption behavior of radionuclides (137Cs and 85Sr) on sand and the influence of pH on the distribution coefficient have been studied. The adsorption obeys the Henry adsorption isotherm, which is an approximation of Freudlich adsorption isotherm, in the concentration range of 10(-9) approximately 10(-12) mol/l for both 137Cs and 85Sr. Their distribution coefficients do not depend on the concentration of radionuclides provided that sand particle size, pH, concentration of coexisting cations and so on are fixed.
