Study of the factors that influence in the determination of extractable organic halogenated compounds (EOX). Validation of the method.

The analysis method of (EOX) extractable organic halogenated compounds is a relatively simple, quick method, that affords a global information (expressed in mg of CI/L) of the organohalogenated compounds either in solid or liquid matrixes. The factors than influence in such a method have been studied and an optimization and validation of the same has been performed. Linearity, precision, accuracy and Limits of detection and quantification of the method have been determined. To finish the study, the interferences of inorganic chlorides in solid and liquid matrixes have been studied in the different range of concentrations.
