| Abstract: | The paper described the basic elements,basic methods and basic operation of quality control that internal standard method of GC/MS was employed for determining PAHs in the soil.The results showed that blank result was less than detection limit.Spiked blank precision was from 7.80% to 25.2%,accuracy was from 49.2% to 96.6%.And spiked samples precision was from 7.77% to 19.8%,accuracy was from 67.2% to 122%.Detection limit was from 0.05 mg/kg to 0.08 mg/kg.The results of determination were scientific,accurate,and could meet the test requirements. |
