Abstract：
The current work aimed to investigate the degradation of the triclocarban (TCC) in aqueous solution using a modified zeolite/TiO2 composite (MZTC) synthesized by applying the electrochemical anodization (ECA). The synthesis process was conducted at different voltages (10, 40, and 60) V in 1 h and using electrophoresis deposition (EPD) in doping zeolite. The MZTC was covered with the array ordered, smooth and optimum elongated nanotubes with 5.1 μm of the length, 120.3 nm of the inner diameter 14.5 nm of the wall thickness with pure titanium and crystalline titania as determined by FESEM/EDS, and XRD. The kinetic study by following Langmuir-Hinshelwood(L-H) model and pseudo first order, the significant constant rate was obtained at pH 11 which was 0.079 ppm/min, 0.75 cm2 of MZTC catalyst loading size achieved 0.076 ppm/min and 5 ppm of TCC initial concentration reached 0.162 ppm/min. The high-performance liquid chromatography (HPLC) analysis for mechanism study of TCC photocatalytic degradation revealed eleven intermediate products after the whole process of photocatalysis. In regard of toxicology assessment by the bacteria which is Photobacterium phosphoreum, the obtained concentration of TCC at minute 60 was less satisfied with remained 0.36 ppm of TCC was detected indicates that the concentration was above allowable level. Where the allowable level of TCC in stream is 0.1 ppm.
摘要：
目前的工作旨在研究三氯卡班（TCC）在水溶液中的降解使用改性沸石/TiO2复合材料（MZTC）通过应用电化学阳极氧化（ECA）合成。合成过程在1小时内在不同电压（10、40和60）V下进行，并在掺杂沸石中使用电泳沉积（EPD）。MZTC被订购的阵列覆盖，光滑和最佳的细长纳米管，长度为5.1μm，通过FESEM/EDS测定的纯钛和结晶二氧化钛的壁厚为14.5nm的内径为120.3nm，和XRD。动力学研究遵循Langmuir-Hinshelwood（L-H）模型和伪一阶，在pH11时获得显著的恒定速率，为0.079ppm/min，0.75cm2的MZTC催化剂负载尺寸达到0.076ppm/min,5ppm的TCC初始浓度达到0.162ppm/min。对TCC光催化降解机理的高效液相色谱(HPLC)分析揭示了光催化全过程后的11种中间产物。关于磷酸光生细菌的毒理学评估，在第60分钟获得的TCC浓度对剩余的0.36ppm的TCC不满意,这表明该浓度高于容许水平。其中料流中TCC的容许水平为0.1ppm。
