An expression descriptive of radionuclide uptake by clays in a slurry has been derived. The function can be linearized in terms of the percent uptake and clay concentration. In linear form, a least square analysis yields two system coefficients, the ultimate uptake and the half dosage. The relationship of half dosage to distribution coefficient, Kd is analyzed. The expression is shown to describe slurry data of many previous investigators, thus indicating its universality for wide variations in clay minerals, cation concentrations and other system variables.
