Web(Qanbarzadeh et al., ACS EST Eng. 2024, 1, 2, 239–248) Fluorotelomer carboxylic acids (FTCAs), however, are often the dominant PFAS in landfill leachate and photocatalytic degradation of these compounds was studied during year one. Following the switch to a VUV photolytic approach, degradation of these compounds in pure water was reexamined.
