This standard BS EN 16166:2021 Soil, treated biowaste and sludge. Determination of adsorbed organically bound halogens (AOX) is classified in these ICS categories:
13.030.01 Wastes in general
13.080.10 Chemical characteristics of soils
This document specifies an operationally defined method for the direct determination of organically bound halogens (chlorine, bromine and iodine) adsorbed and occluded to the sample matrix. AOX being a methodologically defined parameter, it is essential that the procedure is applied without any modification. This document is intended for analysis of sludge, treated biowaste or soil in concentrations ranging from 5 mg/kg dry matter. The upper limit and exact concentration range covered depend on the instrumentation used for determination. NOTE This method can also be applied to other environmental solid matrices, provided the user has verified the applicability.
