The invention relates to a method for removing chlorate ions from solutions by means of catalytic treatment in the presence of hydrogen. According to the invention a rhodium and/or platinum catalyst is used. The choice of catalyst carrier depends on the amount of coadsorbents contained in the solution. The carrier material, which may be oxidic or non-oxidic, should also be easily wettable.
L'invention concerne un procédé d'élimination des ions chlorate dans des solutions, par traitement catalytique en présence d'hydrogène. Conformément à l'invention, on utilise un catalyseur au rhodium et/ou au platine. Le choix du support du catalyseur se fait en fonction de la quantité de co-adsorbants contenus dans la solution. Le matériau support, qui peut être oxydant ou non-oxydant, doit en outre être facilement mouillable.
