Application of F- modified Fe-SAPO-34 as a New Photo-catalyst in Printing and Dyeing Wastewater Treatment

Abstract The development of new photocatalysts with a wide range of applications is one of the important challenges in the field of photocatalysis research. In this thesis, ferric phosphate was used as a transition metal salt, and HF was used as a mineralizer to prepare Fe-SAPO-34 photocatalyst, which was applied to the degradation of organic dye wastewater. The materials were characterized by XRD, SEM and other characterization methods. After the photocatalyst is supported on the molecular sieve, it usually exhibits excellent performance in catalyzing the degradation of different dyes, and generally higher than the catalytic efficiency of the unmodified catalyst under the same conditions.
