Abstract (en)
[origin: WO9948822A1] The invention relates to a method for precipitating or flocculating substances out of solutions, whereby the solution is brought into contact with at least one ion exchanger material. Said ion exchanger material releases ions in the solution which bring about the precipitation or flocculation and/or comprises functional groups on the surface of said exchanger material which bring about the precipitation or flocculation in a catalytic manner.
