AMT - Submersible H2O2 Probe

The determination of Hydrogen Peroxide is one of the most important paramet- ers for the online control in industry. Furthermore, the observation of the oxida- tion processes in industry or in waste water (e.g. to oxidise H2S) is of high in- terest. Because H2O2 is an expensive raw material, there is a permanent demand to save money of course. This new probe system may help here, if the hydrogen peroxide concentration is determined continuously and insitu.

Due to high chemical reactivity of hydrogen peroxide, the determination of H2O2 was difficult until now. Another fact is, that analytical  ethods based on sampling lead mostly to wrong results, even though the sampling and the de- termination have been done very carefully. Another point is, that the alternative volumetric titration is very time consuming and there are permanent costs for chemicals. A sensor or a probe system could allow the continuous reading of the hydrogen peroxide concentration. Titrations can only deliver average con- centrations of a well-defined volume. Fast changes of the concentration or local concentration gradients are only visible with in-situ sensors or probe systems.
All these disadvantages could be avoided, if the new Submersible H2O2 Probe is used for the accurate and reliable insitu determination in depths of up to 100 m (10 bar).
