Abstract

Process for the preparation of ammonium phosphotungstenate as a cation exchanger, characterized in that it comprises the dissolution of phosphotungstenic acid in an organic solvent, the precipitation of ammonium phosphotungstenate by addition of ammonia to the solution, filtration, drying and the washing of the precipitate obtained and the improvement of the mechanical strength of the precipitate by a thermal treatment.
