Abstract (en)
[origin: WO2005113453A1] The invention relates to a method for photocatalytic de-emulsification with the aid of iron ions. The invention relates to a method for the de-emulsification of aqueous organic emulsions. Said method is characterised by the following steps a) addition of an oxidant and an iron compound containing Fe <2+ >or Fe <3+ >ions to an aqueous organic emulsion with a pH value = 5, b) irradiation of the emulsion with UV and/or VIS Light and c) deposition of the formed organic phase.
