Visible-Light-Induced Degradation of Rhodamine B by Wool-Fe Catalyst

Article Preview

Abstract:

The wool fiber was applied for the support to immobilize ferric ion at room temperature, and the wool-Fe complexes obtained were used as heterogeneous Fenton catalyst for the degradation of Rhodamine B under visible light irradiation. Some factors affecting the degradation of dyes such as ferric ion concentration, catalyst dosage and pH values were investigated. In addition, the photo catalytic degradation of dyes was examined by UV-Vis spectra. The results indicated that increasing ferric ion concentration and catalyst dosage in solution led to the higher decoloration rate of dyes with pH≤6.0. The wool-Fe catalyst exhibits an obvious absorption in the visible region and could effectively degrade Rhodamine B in the presence of H2O2 under visible light irradiation.
