The invention relates to a method for disposing of metal cations by binding them to a cationic exchange resin. The aim of the inventive method is to reduce the valency of the metal which produces the metal cations to the smallest possible value. The metal cations whose metal has the smallest possible valency is bound to the cationic exchange resin. The valency of the metal is reduced, for example, by chemical reduction. For this purpose, for example, an organic compound and UV radiation are used.

L'invention concerne un procédé pour éliminer des cations métalliques en les fixant sur une résine échangeuse de cations. Ce procédé vise à réduire à la valeur la plus petite possible la valence du métal qui produit les cations métalliques. Les cations métalliques, dont le métal présente la plus faible valence possible, sont fixés sur la résine échangeuse de cations. La valence du métal est diminuée, par exemple, par réduction chimique. A cet effet, on utilise par exemple un composé organique conjointement avec un rayonnement UV.
