Abstract

This application provides a method and system for measuring the content of soluble organic halogen in water, which includes the use of electrodialysis technology to separate the dissolved inorganic halogen and dissolved organic halogen in the water to be measured, and through the electrodialysis technology, the soluble organic halogen and the solubility Thorough separation of inorganic halogens reduces the use of activated carbon and disposable adsorption columns, simplifies steps, and improves efficiency; adopts photocatalytic technology to convert separated soluble organic halogens into soluble inorganic halogens, without using special high-temperature combustion equipment. It is simple and easy, and the test can be carried out at normal temperature, and it does not need to burn activated carbon and add catalysts, which is more environmentally friendly; and, the instrument with ion analysis function is used to analyze the transformed soluble inorganic halogen to analyze and measure the solubility in the water to be measured The total content index of organic halogen and the content index of each soluble organic halogen (fluorine, chlorine, bromine, iodine).

Description

technical field [0001] This application relates to the field of measuring the total amount of halogenated substances, and in particular to a method and system for measuring the content of dissolved organic halogens in water. Background technique [0002] Dissolved Organic Halogen (DOH) is the total index of many halogenated substances in drinking water and beverages. Due to the coexistence of Dissolved Inorganic Halogen (DIH for short) and DOH in water and the absolute dominance of DIH, the existing technology cannot realize the direct measurement of DOH. Therefore, before measuring DOH, the DIH whose content is absolutely dominant is removed first, then DOH is converted into DIH, and then the DOH index in the water sample is measured. At present, the general DOH measurement steps are divided into three steps, that is, the separation of DOH and DIH by activated carbon, the conversion of DOH into DIH by combustion, the measurement of DIH after combustion conversion, and then...
