A method and an apparatus for determining the total peroxide content of a cellulose pulp suspension in the pulp suspension bleaching stage, wherein the bleaching chemical is peroxide. A sample is taken from the pulp suspension, which sample is measured in a measuring device (25, 25′). Before measuring, the pH of the sample is adjusted and after that the total peroxide content or the perhydroxyl content of the sample is measured, of which measurement the total peroxide content of the sample is determined. |
