Summary

A method is described for the separation of mixtures of halogenated hydrocarbons, adsorbed on charcoal, by controlled thermal desorption. In a second step the desorbed species are burned. The generated halogenide ions are determined coulometrically. The method was applied to real water samples. It can also be applied to determine organic thiocompounds. Thiobenzamide and 2-mercapto-ethanol were used as model substances.
