Abstract
The invention relates to a method for removing polyfluorinated organic compounds from water by means of an adsorbent and to the regeneration of the latter. According to the invention, at least one zeolite is used as an adsorbent, which is brought into contact with the water and is then regenerated by wet-chemical oxidation, wherein the oxidation is carried out by means of UV irradiation and/or at a pH in the range from pH 2.5-7.5.
