Resumen:	The spectrofluorimetric characteristics of 3,3′,4,4′-tetrachlorobiphenyl (TTCB) and 2,3,7,8-tetrachlorodibenzofuran (TTCDF) were studied in aqueous medium and in the presence of cationic, anionic and non-ionic surfactants. It has been established that the fluorescence of binary mixtures of TTCB and TTCDF is enhanced in polyoxyethylene(10)lauryl ether (POLE) using derivative synchronous fluorescence spectrometry at Δλ= 48 nm. Limits of detection of 5.3 ng ml–1 and 2.7 ng ml–1 are obtained, respectively. Good recoveries are obtained when the method is applied to the analysis of binary mixtures of these compounds added to sea-water.
