Abstract

The HPGC determination of Toxaphene in the presence of other chlorinated hydrocarbons with similar retention times is often difficult. This problem can be satisfactorily overcome by including photodehalogenation reactions of interfering substances. Irradiation of the extracts after clean-up procedures in protonated solvents with wavelengths at 254 nm lead to photodechlorinated products of these compounds with shorter retention times, while Toxaphene is mostly stable and can therefore be quantitatively determined by gas-chromatography.
