The Effect of Cation-Exchange Capacity, Clay Content, and Fixation on Rubidium-86 Diffusion in Soil and Kaolinite Systems
1964
Evans, S. D. | Barber, S. A.
An investigation of the factors influencing the diffusion of Rb⁸⁶ in eight soils showed that the more strongly Rb⁸⁶ was absorbed by the soils the slower was the rate of diffusion. In leached soils that were dried after labeling, diffusion was correlated with the amount of Rb⁸⁶ fixed against NH₄OAc extraction. In leached soils that were kept moist after labeling, diffusion was closely related to clay content and exchange capacity. In dilute kaolinite systems, diffusion was related to the amount of Rb⁸⁶ in solution.
