Abstract: | Dielectric spectra of zeolite L (LTL) with potassium ions were measured to investigate movements of potassium ion in it. K,TMA-L was prepared through an ion-exchange of K9-L with tetramethylammonium (TMA) ion, and changed to K,H-L by gentle calcination in air. Since the TMA ion in K,TMA-L was expected to exclusively occupy site D, the hydrogen ion in K,H-L was considered to be located around site D. K9-xHx-L with 0
