Abstract
In this study, a catalyst based on natural zeolite clinoptilolite (CLI), with iron oxide as the active center, was prepared following a two-stage method using ammonium exchange and subsequent metal deposition under ultrasonic irradiation for 40 min at 60 °C. This sonochemical approach significantly shortens the zeolite modification time and increases the specific surface area of the material from 35.4 to 169.5 m2/g. The iron-supported CLI was used to remove methylene blue (MB) from aqueous solution. Simple adsorption removed about 40 % of the initial contaminant, while photo-Fenton conditions reached a removal efficiency of 90 % over 1 h. This result indicates that Fe2+/Fe3+ species near the outer surface of the material effectively activate H2O2 upon exposure to UV radiation.
