This article describes the determination of naphthalene content in coal tar by capillary chromatographic method using DB-5 capillary column(30 m×0.32 mm×0.25μm) and flame ionization detector(FID),and the naphthalene content in coal tar was determined by using the external standard method.The results obtained by this method have good accuracy and precision.The recovery rate of naphthalene in the coal tar was 99.48%~100.51%.The total time needed for sample analysis was no more than 15 min.This method can be used as an effective one.
