This article presents preparation, characterization and evaluation of heterogeneous Fe(III)-SiO(2) catalysts for the photo-Fenton degradation of polyacrylamide (PAM) in aqueous solution. Fe(III)-SiO(2) catalysts are prepared by impregnation method with two iron salts as precursors, namely Fe(NO(3))(3) and FeSO(4), and are characterized by Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) methods. The irradiated Fe(III)-SiO(2) is complexed with 1,10-phenanthroline, then is measured by UV-vis-diffuse reflectance spectroscopy (UV-vis-DRS) and XPS to confirm the oxidation state of Fe in solid state. By investigating the photo-Fenton degradation of PAM in aqueous solution, the results indicate that Fe(III)-SiO(2) catalysts exhibit an excellent photocatalytic activity in the degradation of PAM. Moreover, the precursor species and the OH(-)/Fe mole ratio affect the photocatalytic activity of Fe(III)-SiO(2) catalysts to a certain extent. Finally, the amount of Fe ions leaching from the Fe(III)-SiO(2) catalysts is much low.
