Abstract：An iron(III) Schiff base complex, Fe(III)-bis-Schiff-base-5-sulfonate-salicylalidene-o- phenylenediamine sodium (FeSSPA), was prepared by chemical synthetic method. Immobilized heterojunction photocatalyst FeSSPA-TiO2 was synthesized by alcoholysis method of inorganic titanium salt. UV-Visible diffuse reflectance spectroscopy (UV-Vis DRS) and transmission electron microscopy (TEM) were carried out to characterize the catalysts. The photocatalytic degradation of Rhodamine B (RhB), 2,4-dichlorophenol (2,4-DCP), salicylic acid (SA) under the visible light irradiation and neutral condition (at pH 6.7) were used as probe reactions to evaluate the photocatalytic activities of FeSSPA-TiO2. Under the optimal conditions, RhB was decolored completely in 80 min and DCP, SA removed more than 67%, 100% in 20 h respectively. The mineralized rate of RhB was 70.5% in 33 h. ESR results showed that the highly reactive oxygen species / was produced in the reaction.
