83-2001 Standard Organic Halogen TesterThe operation method of this instrument is basically the same as ISO 9562:1989 and GB/T 15959-1995 "Micro Coulombic Method for Determination of Adsorbable Organic Halogens (AOX) in Water Quality" in accordance with the "Environmental Protection Industry Standard of the People's Republic of China (HJ/T83-2001) for Determination of Water Quality", but the detection method is different. The detection of inorganic halide ions generated by the conversion of organic halogens using ion chromatography can not only determine the total amount of adsorbable organic halogens (AOX) in water (calculated as chlorine). It is also possible to simultaneously measure the levels of adsorbable organic chlorine (AOCI), organic fluorine (AOF), and organic bromine (AOBr) in water.

Principle:

Activated carbon is packed in an adsorption column and pressurized with nitrogen gas to adsorb organic halogen compounds in water. Then, the activated carbon that adsorbs organic halogen compounds is burned and decomposed at high temperatures to convert them into hydrogen halides (hydrides of fluorine, chlorine, and bromine), which are absorbed by alkaline aqueous solutions and separated and determined by ion chromatography.
