| Abstract: | An analytical method was established to determine the content of residual pentachlorophenol in paper packing materials for foodstuffs based on gas chromatography - tandem mass spectrometry. A good linear relationship was obtained in the range from 0.20 to 32.00ng/mL with a coefficient of 0.9996. The limit of quantification was 0.10μg/kg at the condition of S/ N=10. The spiked mean recovery varied from 93.13% to 97.81% and the relative standard deviation changed from 5.64% to 7.64%. This method was applied in the determination of residual pentachlorophenol for 62 kinds of paper packing materials for foodstuffs available commercially, in which pentachlorophenol of low content was detected in three samples. |
