Abstract

Methods, systems and devices for PFAS destruction including adding a sulfite salt to an aqueous solution containing PFAS and then irradiating the aqueous solution with light at 222 nm. The method may include adding a base to the aqueous solution in an amount sufficient to raise a pH of the aqueous solution including PFAS to about 10 or more. It may also include adding a halide salt such as a bromide salt or an iodine salt, and further adding a carbonate. Greater than 90%, or greater than 99%, of the PFAS in the solution may be destroyed by irradiating the aqueous solution in this way.
