Fe2+-NTA synergized UV254 photolytic defluorination of perfluorooctane sulfonate (PFOS): Enhancing through intramolecular electron density perturbation via electron acquisition

•Fe2+-NTA synergized PFOS defluorination under UV254 irradiation at near-neutral pH.•PFOS-Fe2+-NTA becomes more vulnerable with lower transition energy than PFOS anion.•Photo induced electron transfer to PFOS occurred via Fe2+ bridged MLCT process.•Marked electron density perturbation was revealed i...
