Process for removing fluorinated anionic surfactants from gaseous mixtures

摘要

An elimination process of fluorinated anionic sufactants from exhausted gaseous streams, wherein the gaseous stream is put into contact with aqueous solutions having pH in the range from 3.5 to 13.8, the aqueous solution density being lower than 1.05 g/cm<3>, wherein the concentration in the aqueous solution of the fluorinated anionic surfactant removed by the gaseous stream is lower than or equal to 70 ppm.
