Determination of adsorbable organic halogen compounds (AOX)

AOX (adsorbable organic halogens, where X = Cl, Br, I) is a sum parameter that describes the amount of organic halogen compounds in substances such as water, soil and sewage sludge. This parameter is used primarily in waste water analysis. The method for calculating AOX levels is set out in DIN EN ISO 9562. The quantity of organically bound halogens in a water sample is measured using either the shaking method or the column method. In the shaking method, the AOX in a sample are bound to activated carbon by shaking. In the column method, the AOX in a sample are bound to activated carbon by the action of flushing the sample through a glass column filled with activated carbon. The quantity of activated carbon, which is defined precisely in each case, is then burned in an oxygen chamber and the hydrogen halide released is measured by means of argentometry. The amount of fluoroorganic compounds present cannot be measured argentometrically.
