| Abstract: | We determined the amount of polychlorinated biphenyls in fish body by gas chromatography analysis method. The sample was extracted with hexane, purified by concentrated sulfuric acid, concentrated by gas chromatographic method for quantitative analysis. The results showed that the linear range of 7 polychlorinated biphenyls were 0. 001 μg/mL to 0. 20 μg/mL. The standard dosage was 1 μg/kg to 10 μg/kg, recovery of PCB28 , PCB52 , PCB101 , PCB118 , PCB138 , PCB153 and PCB180 were 80% - 105%. The detection limit was 0. 3 μ g/kg. The method was simple and fast. It had good purifying effect and high accuracy. |
