石墨烯-MOF复合半导体催化剂选择性光催化降解废水中柠檬黄染料的行为和机理研究

Tartrazine dye in industrial wastewater can lead to allergies and other serious harms tothe health of children and the residents. Therefore, the timely processing of Tartrazine residue in water environment in order to reduce the harm to human beings has become a pressing matter of the moment. In this study, we will loaded MOF material onto the surface of GO via chemical method. The semiconductor photocatalyst material with recognition function will be prepared by the surface molecular imprinting technique. Then, tartrazine dye in industrial wastewater will degrade under light by using composite photocatalyst material. The selectively photocatalytic degradation of tartrazine dye will be realized. And a new photocatalytic degradation method can be established, which is fast, efficient , selective. We can overcome many proplems of organic dye degradation, such as inefficiency, secondary pollution and non-selective. By adjusting the experimental conditions, the thermodynamics, kinetics, degradation efficiency, selectivity and application conditions of the technical will be iinvestigated in the degradation process in order to provide a powerful technique for the actual wastewater treatment field and establish abundant theoretical foundation for the development of composite photocatalytic materials with selective recognition function in the field of wastewater treatment.
