The photodegradation of terbuthylazine was carried out in a batch reactor，in which the TiO2（or Fe3+）photocatalyst was mixed with a 80 m L solution of 7 mg/L terbuthylazine（C9H16ClN5，99.4%purity）.The light source was a 200 W xenon lamp（CMH250，Instruments of Beijing Normal University，China）equipped with a 420 nm cutoff filter.The light intensity of the Xe lamp reaching the surface of the reactor was 80 W/m2，and the experimental condition was denoted as Vis（for visible light）.Anatase TiO2（KY-TiO2-01，Shanghai Cai Yu Nano Technology Co.，Ltd.，China）and rutile TiO2（KY-TiO2-03，Shanghai Cai Yu Nano Technology Co.，Ltd.，China）were used as catalysts and labeled as TIO-A and TIO-R，respectively.Their characteristic parameters，based on the results of X-ray diffraction（XRD）（D/max 2500PCX，Rigaku Japan） and Brunauer–Emmett–Teller（BET）analysis（Flow Prep060，Micrometrics，USA），are shown in Table 1.Except when stated otherwise，all the experiments were conducted under fixed conditions according to our previous study（Li et al.，2014b），initial pH 3.3，1.32 mmol/L of H2O2，1 g/L of TiO2photocatalyst，and 34 mg/L of Fe3+（FeCl3）.
