摘要
探讨了关于石墨烯基复合材料处理模拟废水的研究。考察了TiO_2/RGO和Fe_3O_4/RGO对酸性品红和亚甲基蓝的处理情况,并进行了表征。在TiO_2/RGO体系中,酸性品红的去除效果最高可达到74.01%;亚甲基蓝的去除效果最高可达到94.79%。在Fe_3O_4/RGO体系中,酸性品红的去除效果最高可达到78.55%;亚甲基蓝的去除效果最高可达到98.02%。研究结果表明,磁性石墨烯Fe3O4/RGO的处理结果比TiO_2/RGO效果好。
This paper explores the treatment of simulated wastewater from graphene-based composites. The treatment of acid fuchsin and methylene blue by TiO_2/RGO and Fe_3O_4/RGO is investigated and characterized. In TiO_2/RGO system, the removal effect of acid fuchsin can reach up to 74.01%; the removal effect of methylene blue can reach up to 94.79%. In Fe_3O_4/RGO system, the removal effect of acid fuchsin can reach 78.55%; the removal effect of methylene blue can reach 98.02%. The results show that the magnetic graphene Fe_3O_4/RGO treatment result is better than that of TiO_2/RGO.
