The rates of sodium-hydrogen exchange on thoria and on zirconium phosphate in two particle sizes were measured both by titration and potentiometrically in limited bath experiments over a sodium ion concentration range centration within this range, and the results indicate that the rate controlling process is the diffusion of ions through the exchanger particles. Further evidence in support of particle diffusion is afforded by infinite bath cesium-potassium exchange experiments on zirconium phosphate using a tracer technique. The effective diffusion coef ficient for the sodium and hydrogen ions in the thoria exchanger ranges from about 4-15 x 10/sup -8/ cm/sup 2/-sec. (auth)
