摘要：In recent years, as the production and use of dyes have been greatly developed, the treatment of dye wastewater has become one of the current environmental problems that must be resolved. Ozone (O3) is a strong oxidant and is widely used in water treatment. In this study, the interaction process of ozone-treated Direct Red 80 (otDR80) and human serum albumin (HSA) was explored using multi-spectra methods. The results showed that otDR80 made the skeleton structure of HSA loosened and unfolded. OtDR80 changed the secondary structure of HSA, making the chromophore in the hydrophobic interior of HSA more tightly packed. The intensity of RLS spectra showed a upward trend after exposure to otDR80, indicating that the size of the reaction system increased. This study provides a new method for the degradation of DR80 and its toxicological study at the molecular level. study at the molecular level.
