Halogenated Organic Compounds (AOX)

AOX stands for 'Adsorbable Organically bound halogens' expressed as chloride, and determined according to the relevant European Standard method. AOXs are substances that are adsorbed from water onto activated carbon. They may be volatile substances like trichloromethane (chloroforme), chlorophenoles and chlorobenzenes or complex organic molecules like dioxins and furans. Most AOXs are chlorine-containing molecules, but bromo- and iodo-AOXs may also occur.
