摘要：

By controlled flow pyrolysis conditions, various combinations of di-, tri-, and tetrachlorophenols were reacted to form tetrachlorodibenzo-p-dioxins (TCDD). These reaction products were separated by high performance liquid chromatography (HPLC) and were characterized by gas chromatography-mass spectrometry (GC-MS). This combination of HPLC and GC-MS allowed assignment of identity to all 22 isomers of TCDD. Applications of this selective analysis to determination of TCDD in a variety of samples are also discussed.
