Characterization of sludges - Determination of adsorbable organically bound halogens

Scope

This European Standard describes an empirical method for the direct determination of an amount ranging from 5 mg/kg to approximately 6 g/kg dry matter in sludge of organically bound chlorine, bromine and iodine (but not fluorine) adsorbed and occluded to the sludge matrix. Non-volatile organically bound halogens adsorbable on activated carbon present in the aqueous phase of sludge prior to drying are included in the determination.
NOTE The upper range of the method is instrument dependent.
