摘要
为降解废水中的阿奇霉素,用溶胶-凝胶法制备了Ti O_2,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 O_2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 O_2光催化剂(Ti O_2-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 O_2-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%。
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%.
