The method for determination of AOX (absorbable organically bound chlorine) in water has been developed on the basis of the existing ISO 9562 standard and has been certified within the Russian national standard system GOST R 8. 563. The method can be applied to environmental and analytical control and monitoring of chlorinated organic compounds occurring in the environment.

  In accordance with the proposed method, organochlorine substances are concentrated by adsorption on the activated charcoal, are incinerated in an oxygen flow at 9500 C, and chloride-ions thus formed are detected microcoulometrically. The method is intended for organochlorine compounds discharge regulation to meet the international AOX limitations, based on the «best available techniques» principle; for optimization of water treatment technology in order to minimize the amount of organochlorine substances in drinking water; for monitoring the environment (fresh and marine water, snow and rain water), and for indication of potential organochlorine pollution sources.
