Abstract
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.
