Abstract
Procédé et dispositif de mesure de la concentration de peroxyde d’hydrogène Le procédé de mesure comprend les étapes suivantes :- injection d’un flux continu dudit liquide dans une cellule (21) contenant un catalyseur (23) adapté pour catalyser la décomposition du peroxyde d’hydrogène ;- mesure de la quantité d’oxygène et de la quantité de dioxyde de carbone en régime stationnaire dans le flux de gaz produit par la cellule (21) ;- détermination de la concentration de peroxyde d’hydrogène dans le liquide en utilisant ladite quantité d’oxygène mesurée et ladite quantité de dioxyde de carbone mesurée. Figure pour l'abrégé : Figure 2Method and device for measuring the concentration of hydrogen peroxide The measuring method comprises the following steps: - injection of a continuous flow of said liquid into a cell (21) containing a catalyst (23) suitable for catalyzing the decomposition of the peroxide of hydrogen; - measurement of the quantity of oxygen and the quantity of carbon dioxide in a steady state in the gas flow produced by the cell (21); - determination of the concentration of hydrogen peroxide in the liquid in using said measured amount of oxygen and said measured amount of carbon dioxide.
