Claim 0:
1. An apparatus for destroying recalcitrant perfluoroalkyl substances, comprising:
a first vessel having an adsorption bed formed from a porous, hydrophobic, hydrothermally stable molecular sieve;
a source of compressed air coupled to the first vessel for introducing compressed air into the first vessel;
a source of heat coupled to the first vessel that can selectively increase a temperature of the first vessel to a first temperature between 80 and 120 degrees Celsius and to a second temperature of at least 150 degrees Celsius;
a source of ozone coupled to the first vessel for introducing ozone into the first vessel;
a second vessel coupled to the first vessel to receive any off-gases from the first vessel and including a catalytic bed formed from a zeolite-supported CaO catalyst;
a catalytic oxidizer coupled to the second vessel and having a metal-oxide supported noble catalyst operating at a temperature of between 200 and 350 degrees Celsius; and
a source of a mineral acid coupled to the second vessel.
