The Determination of 19 Chlorophenol Concentrations in Leather Products
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%).
