Title (EN) A METHOD OF OXIDATION
(FR) PROCEDE D'OXYDATION
Abstract:
(EN) Electrochemically regenerated RuO4 (or corresponding oxides of Os, Ir, Rh) is used in the decomposition of matter, especially matter containing organic material. The method has particular advantage in dealing with compounds containing chlorine and, in a development, provides for the removal of heteroatoms N, Cl, P, As, S, avoiding contamination with unoxidised organics and/or Ru (or Os, Ir, Rh as the case may be).
(FR) La présente invention concerne l'utilisation de RuO4 régénéré par procédé électrochimique (ou les oxydes correspondants en Os, Ir ou Rh) pour la décomposition de matières, particulièrement de matières organiques. Ce procédé, qui convient particulièrement au cas où l'on a affaire à des composés chlorés, assure, grâce à l'une de ses réalisations, l'élimination des hétéroatomes de N, Cl, P, As, et S, ce qui évite la contamination par des matières organiques non oxydées et/ou par le Ru (ou Os, Ir ou Rh suivant le cas).
