Zusammenfassung:	A method is provided for (i) separating a first water-soluble or water-dispersible bio-affecting substance, contained in a liquid medium, from one or more other components of the liquid medium, said other components being selected from impurities and other water-soluble and/or water-dispersible bio-affecting substances, and/or (ii) purifying the first bio-affecting substance contained in the liquid medium together with said one or more other components, the method comprising: forming a mixture comprising the liquid medium and particulate polymeric adsorbent, the adsorbent forming a complex with the first bio-affecting substance or with said other component(s); and subjecting the liquid medium, containing the complex, to membrane filtration. The method of the invention enabales the disadvantages and limitations of known separation and purification processes to be overcome or minimised.
