MEASUREMENT OF AOX FOR THE SCREENING OF HALOGENATED ORGANIC-COMPOUNDSIN WATER

This paper describes the procedure for determining AOX (Adsorbable Org anic Halogens), referring to the two main carbon adsorption methods, a nd to the procedures of combustion in an oven and to the coulometric t itration of the halogen. Tests performed with the method of adsorption on a microcolumn are described and the analytical accuracy briefly di scussed. The paper also describes the possible fields of application o f the AOX technique, its limitations and extensions such as the EOX (E xtractable Organic Halogens), and POX (Purgcable Organic Halogens) tec hniques.
