This method is feasible to determine and confirm contents of pentachlorophenol in textile auxiliaries via GC-ECD method. The testing samples are extracted by steam distillation ,the extract solution are extracted with n-hexane by acetic anhydride acetylization .Determination and confirmation is made by GC-ECD （gas-chromatography with an electron capture detector）, using extermal standard method. Through the optimization ,the experimental data show tha ：the corresponding recovery is 88.2%- 102.1%, the precision is 8.0%-9.2%, and the limit of determination is 10μ/kg .All the technical items conform to the requirements.
