This article discusses the determination of 19 chlorophenol concentrations in leather products using gas chromatography-mass spectrometry.This article uses the method of steam distillation to extract chlorophenol from the sample.The distillate is collected into a conical flask containing potassium carbonate powder to form a solution,which is then acetylated with acetic anhydride.After being extracted with n-hexane,it is detected by gas chromatography-mass spectrometry and internal standard injection method.This method has good linear relationship(R2＞0.99),good repeatability(0.011％～0.029％),good stability(0.010％～0.032％),good precision(0.044％～0.088％),and good recovery rate(91.2％～98.4％).
