Description:
A total organic halogen (TOX) analysis directly measures halogen (Cl, Br, I) covalently bound to organic molecules in a sample. Currently, the most popular method for TOX in water involves carbon adsorption, oxidative combustion, followed by measurement of the formed hydrogen halide by microcoulometry. TOX can be used as an indicator of water quality and in water treatment for unit process design and control. TOX can be a direct measure of disinfection by-product formation or, in some circumstances, a surrogate measure of individual organic pollutants. Individual circumstances must be carefully judged to determine the usefulness of TOX in these applications.
