Total Organic Halogens
Total Organic Halogens (TOX), often referred to as Total Organic Halides, is the sum parameter of Total Organic Fluor (F), Chlorine (Cl), Iodine (I) and Bromine (Br). Total Organic Halogens are measured by adding the amount of Purgeable Organic Halogens (POX) to the amount of Adsorbable Organic Halogens (AOX) measured in a water sample. An elemental combustion analyzer is able to measure the POX and AOX content in (waste)water samples according to Oxidative Combustion Microcoulometry.
International method to measure the amount of Total Organic Halogens (TOX) in water samples: EPA 9020
