    摘要: A method and system for determining the content of hydrogen peroxide in an aqueous solution are described. The solution is brought to a pH below 6, supplied with excess I⁻ and catalyst, and irradiated with light, the absorbance being measured at a predetermined wavelength. The system comprises a hydrogen peroxide containing solution (15), e.g. from a swimming pool, an analyser (20) and a microcomputer (4) for controlling the system. A monochromatic light source (2) transmits light through the sample in the analyser cuvette (1) to a photocell (3) connected to the microcomputer (4). A display (5) is also connected to the microcomputer (4). Supply of sample and reagents from reagent tanks (10,11) to the cuvette (1) is controlled by the microcomputer (4). The method of system can be used to control the supply of hydrogen peroxide to an aqueous system.
