The invention relates to a method for the online determination of the hydrogen peroxide content in a mixture formed during a chemical reaction. The inventive method comprises the following steps: (1) at least one reagent is added to the mixture containing hydrogen peroxide, forming a substance, said reagent combined with hydrogen peroxide being suitable for the formation of a substance which can be detected by means of optical methods, and (2) the content of the substance is determined by measuring its specific absorption in a wavelength range which is suitable therefor.
L'invention concerne un procédé pour déterminer en circuit la teneur de peroxyde d'hydrogène dans un mélange résultant d'une réaction chimique. Le procédé selon l'invention comprend au moins les étapes suivantes : (1) ajout au mélange contenant le peroxyde d'hydrogène d'au moins un réactif apte à former avec le peroxyde d'hydrogène une substance détectable par des méthodes optiques et formation de la substance ; (2) détermination de la teneur de la substance par mesure de son absorption spécifique dans un domaine spectral convenant à cet effet.
