摘要：

Iron modified zeolites represent interesting group of catalysts suitable for organic compounds removal from waste streams. In this work the MFI structured catalysts with various Fe contents incorporated by isomorphous substitution were prepared hydrothermally using two methods with different sources of silica and iron. The structure of the catalysts was tested by XRD, contents of Fe were determined by XRF, Fe centers were characterized by UV-Vis spectroscopy, and BET isotherms were used for porosity measurements. Iron silicate MFI catalysts were used in catalytic phenol removal from water by wet peroxide oxidation in batch arrangement. Catalysts with at least 1% of Fe provided full phenol conversion after 5 h of reaction.
