摘要： 为降解废水中的阿奇霉素，用溶胶-凝胶法制备了TiO2，改进Hummer's法制备了氧化石墨烯（GO），并在无水甲醇介质中，以TiO2为催化剂，紫外灯（UV-B）为光源，经催化还原得到石墨烯负载TiO2光催化剂（TiO2-RGO）。对催化剂进行了表征。在光化学反应器中以紫外灯为光源，TiO2-RGO-X为光催化剂降解溶液中的阿奇霉素。结果表明，阿奇霉素降解率可达到98%。

Abstract: To degrade azithromycin in wastewater,TiO2 has been prepared by sol-gel method,and graphene oxide (GO) prepared by improved Hummer's method. Then,the grapheme-loaded TiO2 photo-catalyst(TiO2-RGO) could be obtained through catalytic reduction,in absolute methanol media by means of TiO2 as catalyst,and UV as the source of light. The catalyst was characterized. In a photochemical reactor,UV was used as light source and TiO2-RGO as photo-catalyst for the degradation of azithromycin in solution. The result shows that the degradation rate of azithromycin reaches 98%.
