环氧四环素(Oxytetracycline，OTC)又称土霉素，属于四环素类广谱抗生素，作为抗菌剂和饲料添加剂被广泛地应用于人类和动物，具有潜在的生态毒性，目前尚未找到一种理想而有效的处理方法。本研究采用光催化氧化法对其进行光催化降解实验。TiO2以其化学稳定性、无毒性、价格低廉、光催化活性高等优异性能被广泛研究。但因其颗粒过小，易团聚，不易与水分离，吸附能力差，需紫外光激发而受到限制。 本研究以具有大表面、高吸附性能的沸石为载体，以具有优异的导电性能、较高的比表面积、可最大限度地拓展光催化剂对可见光的响应范围的石墨烯掺杂，采用固态分散法制备石墨烯/二氧化钛/沸石(Graphene/TiO2...Oxytetracycline(OTC), an important member of tetracycline and is popularly used in humans and animals, which is reported to be a toxic threat to the ecosystem. It is important to find the treatment method which has high removal efficiency for actual use since OTC are not biodegradable. In this study, the photocatalysis was used to degrade the OTC. TiO2 is a promising photocatalyst which is stable...学位：理学硕士院系专业：环境与生态学院_生态学学号：3332013115170
