ISO2004-Allrightsreserved ISO9562:2004(E) Introduction Adsorbable organically bound halogens (AOx) is an analytical convention. The result is a parameter used for not fluorine) that can be adsorbed on activated carbon under specified conditions and, if the sample is not filtered, includes that associated with suspended matter. The user should be aware that particular problems could require the specification of additional marginal conditions.
