Novel Defluorination Pathways of Perfluoroether Compounds (GenX): α-FeO Nanoparticle Layer Retains Higher Concentrations of Effective Hydrated Electrons.

The development of efficient defluorination technology is an important issue because the kind of emerging pollutant of hexafluoropropylene oxide dimer acid (GenX) as an alternative to perfluorooctanoic acid (PFOA) has the higher environmental risks. In the UV/bisulfite system, we first developed a hydrophobic confined α-FeO nanoparticle layer rich in oxygen vacancies, which accelerated the enrichment of HSO and GenX on the surface and pores through electrostatic attraction and hydrophobic interaction, retaining more hydrated electrons (e) and rapidly destroying GenX under UV excitation. Especially, under anaerobic and aerobic conditions, the degradation percentage of GenX obtain nearly 100%, defluorination of GenX to 88 and 57% respectively.
