    Procedure for the elimination of organic dyes from industrial effluents. The present invention relates to a process for decolorization of effluents and/or aqueous solutions, containing at least one organic dye of the class anthraquinone, indigo, iminoquinone, nitrosated and nitrated dyes, metal complex dyes, polyene dyes and dyes of methine and polymethine by catalytic hydrogenation reactions, comprising a step in which the effluent or solution is contacted with a catalyst based on noble metals supported on a solid and a reducing agent.

    In the present invention, "supported catalyst" means a catalyst based on a noble metal that is found on the surface of the solid covering it, dispersed on the surface of the solid or inside it.
    In a particular embodiment of the present invention, the noble metal of the supported catalyst is selected from palladium, platinum, rhodium, ruthenium, or any mixture thereof. More particularly, the catalyst comprises palladium.
    In a particular embodiment, the catalyst comprises between 0.1-7% by weight and more preferably between 0.1 and 2% by weight of Pd or Pt or Rh or Ru or any of their mixtures.
