Ionic Relationships in Clay Suspensions and Dialyzates: I. Rubidium-86 as a Tracer for Potassium1

R. E. Franklin and G. H. Snyder2

ABSTRACT

Highly significant linear correlations were found to exist between radiotracer quantities of Rb86 and the K concentrations of the dialyzate phases of clay-water membrane equilibrium systems. The systems extended over a wide range of Ca/K saturation ratios, electrolyte concentrations, and pH values. The linear regression lines for bentonite, illite, kaolinite, and vermiculite systems had similar slopes. The actual amounts of K in the dialyzate phases were about 1.4 times the values indicated by the Rb tracer. Of the four clay minerals only the vermiculite presented problems because of specific fixation of K or Rb. Uptake of K42 by excised barley, corn, and soybean roots from bentonite systems was also significantly correlated with uptake of Rb86. It appeared that Rb86 could be used in tracer quantities to reflect relative changes in the K distribution in these systems.
