Abstract
The present disclosure relates to the technical field of degradation of persistent pollutants and discloses a method for efficiently degrading a perfluorinated compound (PFC), through which the problems of harsh reaction conditions and less high defluorination rate existing in prior-art methods for degrading PFCs are solved. In the present disclosure, a 3-indoleacetic acid (IAA) solution is irradiated with 254 nm UV light to generate hydrated electrons, with which the PFC are degraded by reduction under an aerobic condition, where an organo-modified montmorillonite is added to provide a reaction microzone, so the degradation and defluorination effects of the hydrated electrons for the PFC are greatly improved. The method for degrading a PFC according to the present disclosure is not affected by the pH of and the dissolved oxygen in the solution and less affected by the humic substances in a water body, thereby overcoming the defects in existing methods for degrading PFCs with hydrated electrons while the degradation efficiency is ensured. Therefore, the present disclosure is of great application value.
