Title:
METHOD AND SYSTEM FOR MEASURING CONTENT OF DISSOLVED ORGANIC HALOGENS IN WATER
Document Type and Number:
WIPO Patent Application WO/2017/202029
Kind Code:
A1
Abstract:
A method and system for measuring the content of dissolved organic halogens in water. The method comprises separating dissolved inorganic halogens from dissolved organic halogens in water to be measured by means of an electrodialysis technique (S1), wherein the electrodialysis technique is carried out to realize thorough separation of the dissolved organic halogens and the dissolved inorganic halogens, so as to reduce the use of an active carbon and a disposable adsorption column, simplify steps and improve the efficiency; converting the separated dissolved organic halogens into the dissolved inorganic halogens by means of a photocatalysis technique (S2), wherein a special high-temperature combustion device is not needed, the operation is simple and easy, testing can be performed at a normal temperature, combustion of the active carbon and addition of a catalyst are not needed, and this is more environmentally friendly; and analysing the converted dissolved inorganic halogens using a device with an ion analysis function (S3), so as to analyse and measure a total content index of the dissolved organic halogens and a content index of each of the dissolved organic halogens (fluorine, chlorine, bromine and iodine) in the water to be measured.
