Abstract

1. A process for determining and monitoring hydrogen peroxide concentrations in liquid reaction media by reaction of the hydrogen peroxide in a component stream of the reaction medium with a substance which reacts off completely with hydrogen peroxide and measuring the associated physical and/or chemical effects, characterized in that a substance which reacts with hydrogen peroxide in an exothermic reaction is used as the reacting substance, in that the component stream of reaction medium and a stream of the reacting substance are combined in a heat-insulated measuring cell and in that the increase in the temperature of the mixture arising out of the heat reaction is measured, the reacting substance having to be present in excess in relation to the hydrogen peroxide.
