Abstract: A process for the on-line determination of the hydrogen peroxide content of a mixture obtained in a chemical reaction comprises at least the following steps: (1) admixing the mixture comprising hydrogen peroxide with at least one reagent which is capable of forming a substance which can be detected by optical methods on reaction with hydrogen peroxide, so as to form this substance, (2) determining the amount of the substance present by measuring its specific absorption in an appropriate wavelength range.
