Abstract

The changes in ion-exchange characteristics of synthetic mordenite ground by a planetary ball mill under dry conditions were investigated using radioisotopes of ¹³⁷Cs and ⁸⁵Sr as tracers. The self- diffusion of Cs⁺ in the mordenite sample was facilitated in the initial stage of grinding, while it was leveled off for the further operation. The relative amount of Cs⁺ immediately exchanged in the mordenite sample was gradually styptic to a constant value with increase in grinding time after showing a rapid reduction in amount in the early stages of grinding. High selectivity of the mordenite sample for Cs⁺ against Sr²⁺ observed in acidic solution diminished obviously with an increase in grinding time.
