AOF, AOCl, AOBr, AOI, and AOX by Combustion Ion Chromatography

Adsorbable organically bound halogens (AOX) is the sum parameter for organically bound halogens in water. The organic compounds are adsorbed to active carbon and subsequently combusted. Determination of the sum of chloride, bromide, and iodide is traditionally performed by titration.

With Combustion IC, it is possible to determine the individual halogens (AOCl, AOBr, AOI) as well as fluorine (AOF) which cannot be determined by the argentometric titration method.

Keywords: AOX (adsorbable organic halogen), AOCl (adsorbable organic chlorine), AOBr (adsorbable organic bromine), AOI (adsorbable organic iodine), AOF (adsorbable organic fluorine)
