Abstract:This paper explores the treatment of simulated wastewater from graphene-based composites. The treat- ment of acid fuchsin and methylene blue by TiO2/RGO and Fe3O4/RGO is investigated and characterized. In TiO2/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 Fe3O4 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 Fe3O4/RGO treatment result is better than that of TiO2/RGO.
