The ion-exchange process using a natural clinoptilolite zeolite with Zn, Mn and Cu ions was evaluated. The existence of these transition metals in the samples was detected by DC arc-AES. XRD spectra showed that after exchanging the HEU zeolite structure was retained. These samples were tested as potential catalysts for ozone decomposition at ambient temperature. A Zn- containing form was not active, whereas a Cu-exchanged sample showed about 15% conversion and Mn-loaded zeolite showed about 32% conversion at the beginning of ozonation. Deactivation of all investigated samples was observed.
