WebPhotochemical processes offer feasible methods for PFAS decomposition due to their simplicity, operating in mild conditions, and high degree of efficacy. This paper identifies and compares mechanisms of photo-chemical/catalytic oxidation and reduction of different PFAS structures. WebNov 15, 2015 · Reductive decomposition of PFOS is possible, however it is still limited because high reduction potential is needed to defluorinate saturated or unsaturated perfluorocarbons (E < −2.7 V) [14]. So far, it has been reported that PFOS can be reduced by zero-valent iron in subcritical water but the operation conditions are strict (350 °C, 20 MPa …
