Abstract
The present disclosure relates to a degradation method of a perfluoroalkyl substance (PFAS). The degradation method includes the following steps: polymerizing indole to synthesize pind; and mixing synthesized pind with the PFAS to form a mixed solution, and illuminating the formed mixed solution to allow pind to generate hydrated electrons (eaq−) for degrading the PFAS. In the degradation method of the present disclosure, indole with a high yield of hydrated electrons is polymerized to generate pind, and pind is used as a precursor for the generation of the hydrated electrons to increase the stability of a molecular structure of pind through a highly conjugated structure formed after polymerization, thereby achieving the purpose of continuously generating the hydrated electrons under ultraviolet irradiation and effectively degrading PFASs, which is of great significance for addressing the environmental pollution problem of PFASs.
