【摘要】 为降解废水中的阿奇霉素,用溶胶-凝胶法制备了Ti O₂,改进Hummer’s法制备了氧化石墨烯（GO）,并在无水甲醇介质中,以Ti O₂为催化剂,紫外灯（UV-B）为光源,经催化还原得到石墨烯负载Ti O₂光催化剂（Ti O₂-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,Ti O₂-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%。更多还原

【Abstract】 To degrade azithromycin in wastewater,TiO₂has been prepared by sol-gel method,and graphene oxide（GO）prepared by improved Hummer’s method.Then,the grapheme-loaded TiO₂photo-catalyst（TiO₂-RGO）could be obtained through catalytic reduction,in absolute methanol media by means of TiO₂as 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%.更多还原
