Elimination process of fluorinated anionic surfactants

An elimination process of fluorinated anionic sufactants from exhausted gaseous streams wherein the gaseous stream is put into contact with aqueous solutions having pH from 3.5 to 13.8, the aqueous solution density being lower than 1.05 g/cm3, preferably lower than 1.03 g/cm3, wherein the concentration in the aqueous solution of the fluorinated anionic surfactant removed from the gaseous stream is lower than or equal to 70 ppm, preferably lower than or equal to 60 ppm, still more preferably lower than 50 ppm.
