Abstract

 Background & Aims of the Study: Terfetalic Acid (TPA ) is produced in large quantities and used in various industries. Besides, TPA is among the main sources of water pollution in industrialized countries. TPA photo-degradation process was performed in a Circulating Fluidized Bed Reactor (CFBR) by one Ultraviolet type A (UV-A) lamp and ozone generator with MnFe2 O4 /Willemite photo-catalyst. Materials and Methods: In this research, the nanoparticles of MnFe2 O4 and Willemite were synthesized by co-precipitation reactions and wet mixing method, respectively. Then MnFe2 O4 / Willemite was synthesized by the immobilization of MnFe2 O4 on Willemite by mechanical method. Full factorial experimental design with 4 factors, including the pH, the initial concentration of TPA, the amount of Catalyst (Cat. ), and O3 dosage was used for modeling and optimizing the process. Results: In the optimal conditions, the amounts of pH, TPA, Cat., and O3 were obtained equal to 9, 20 ppm, 1. 5 g/L, and 2. 17 mg/h, respectively. In these conditions, degradation efficiency was obtained to be 98. 2695%, and Decomposition kinetics was determined as pseudo-first-order with Kapp =0. 2707 min-1, kLH =3. 729 ppm min-1, and kadd =0. 051 ppm-1. Conclusion: Comparing experiments results in different processes, such as UV, UV-Cat, O3, UVO3, Cat-O3, and UV-Cat-O3 revealed that photo-catalytic ozonation (O3 /MnFe2 O4 /Willemite) in the presence of UV for degradation of TPA in an aqueous environment, present the higher efficiency.
