| Abstract: | Polymeric metacyclophaneoctol-based sulfonic acids have been synthesized, and their ion-exchange properties have been studied. New polymeric sulfonic acids have been obtained through the sulfonation of network polymers based on immobilized cis-metacyclophane-3,5,10,12,17,19,24,26-octols. The structure of the polymers has been investigated by means of IR spectroscopy, potentiometric titration, and elemental analysis. The polymers thus obtained possess a high ion-exchange capacity with respect to Na+, Cu2+, Pd(NH3)4]2+, and In3+ cations in a wide pH range. Selectivity coefficients of Na+-H+, Cu2+-H+, and In3+-H+ ion exchange have been estimated. |
