Abstract:

Absorbable organic halogens (AOX) are an indicator of industrial water pollution. The AOX are defined as the fluorine, chlorine, and bromine compounds absorbed from water by activated carbon. To measure the AOX we applied combustion ion chromatography. The activated carbon containing the AOX was combusted in an oxygen atmosphere by an automated combustion instrument. The resulting gas was trapped in an absorbing solution, where fluoride, chloride, and bromide represent the water’s organic halogens. A portion of the absorbing solution was automatically transferred to an ion chromatography system to measure the halogen anions. This method accurately measured AOX in wastewater.
