中文摘要：
运用化学合成方法制备了双（5-磺酸钠水杨醛）邻苯二胺席夫碱[N,N＇-Bis-schiff-base-5-sulfonate-salicylalidene-o-phenylenediamine sodium,SSPA]铁（III）配合物（FeSSPA）,采用无机钛盐醇解法制备了席夫碱铁-TiO2复合物催化剂（FeSSPA-TiO2）.通过紫外-可见反射光谱（UV-Vis DRS）、透射电镜（TEM）对制备催化剂进行了表征.利用FeSSPA-TiO2可见光（λ〉420 nm）激发活化分子氧降解有机染料罗丹明B（Rhodamine B,RhB）、无色小分子2,4-二氯苯酚（2,4-Dichlorophenol,2,4-DCP）及水杨酸（Salicylic acid,SA）,研究了FeSSPA-TiO2的光催化性能.结果表明,FeSSPA-TiO2光催化剂在pH 6.7,可见光照射条件下,80 min RhB褪色率达到100%,20 h小分子2,4-DCP,SA的降解率分别达到67%,100%.在实验条件下,33 h对RhB矿化率达到70.5%.通过反应过程中氧化物种的测定,发现降解过程主要涉及超氧自由基（·O-2）的氧化机理.
英文摘要：
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 heterojunc-tion 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 op-timal 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 reac-tive oxygen species.O2 was produced in the reaction.-/.OOH
