摘要：

The analysis of XRD, the analysis of hydroxyl radical, the analysis of degradation rate and the experiment of N-2 were carried out to investigate the enhanced mechanism of TiO2 photocalysis by Fe3+. It was found that the degradation rate of Sulfadiazine (SD) was enhanced by Fe3+ in TiO2 suspended solution, and the crystal form of TiO2 was stable during the Fe3+ strengthening process, and the yield of hydroxyl radical was enhanced by Fe3+ effect in suspended solution. Furthermore, the mechanism of SD degradation we propose here was mainly from the Fe3+ ion loading on surface of TiO2 as electron acceptor to enhance the yield of hydroxyl radical which enhanced the degradation rate of SD in suspended solution, and the part of hydroxyl radical produced by Fe3+ ion strengthened the degradation of SD in solution.
