Zusammenfassung:	Waste waters which, in addition to water-soluble inorganic salts, contain water-soluble organic phosphorus compounds, in particular sulphonated arylphosphines and, possibly, other organic impurities, for treatment, first receive an addition of an inorganic acid and are then extracted by a water-insoluble amine. According to a particular embodiment, the inorganic acid is used in the form of a salt of the amine used as extraction medium.
