| Abstract: K-type mordenite has been synthesized by acid advancing, and its properties of ion exchange for alkali ions like saturation capacity of exchange, distribution coefficient and the pH titration curve have been determined, K-type mordenite was researched by X-ray diffraction and FT-IR. These results show that K-type mordenite synthesized by acid advancing has better remembering and selectivity of ion-exchange for K+ . |
