Perfluorooctanoic acid (PFOA) has a great environmental challenge due to the environmental persistence, and bioaccumulation potential to the natural environment. For this purpose, flavin mononucleotide (FMN) functionalized to the surface of colloidal titanium dioxide (TiO2) nanoparticles was used as a catalyst for PFOA reduction, the results showed high reduction efficiency toward acid (PFOA). The process involved generating the catalyst in which FMN was reduced to FMNH2 by accepting two excited electrons from the conduction band of TiO2 nanoparticles during a photoirradiation process. Following the photoirradiation process, the FMNH2was reacted with the PFOA in anaerobic condition with reactions taking place at 65 oC and a pH of 7.5. Reduction products of PFOA were determined using LC-MS/MS, and the monitoring concentration and rate constant of PFOA were conducted on a GC/MS.
