DETERMINATION OF HYDROGEN PEROXIDE CONCENTRATIONS

摘要

For amperometric determination of the hydrogen peroxide concentration in a fluid sample, different electrical voltage steps are applied to the electrodes. In this process, at least one voltage is suitable for measuring the hydrogen peroxide concentration in the fluid sample, and at least one additional voltage is suitable for measuring the concentration of a substance in the fluid sample that acts as an interfering substance during measurement of the hydrogen peroxide concentration.
