Effect of dry grinding on iori-exchange characteristics of synthetic mordenite

Effect of dry grinding on iori-exchange characteristics of synthetic mordenite The changes in ion-exchange characteristics of synthetic mordenite ground by a planetary ball mill under dry conditions were investigated using radioisotopes of 137 Cs and 85 Sr 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 Sr 2+ observed in acidic solution diminished obviously with an increase in grinding time. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Amphibia-Reptilia Brill

Abstract

The changes in ion-exchange characteristics of synthetic mordenite ground by a planetary ball mill under dry conditions were investigated using radioisotopes of 137 Cs and 85 Sr 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 Sr 2+ observed in acidic solution diminished obviously with an increase in grinding time.
