| 摘 要： | 目的探讨水﹑气﹑土壤中多环芳烃检测标准(HJ 478-2009﹑HJ 647-2013、HJ 784-2016)的正确出峰时间和顺序。方法用高效液相色谱来对苊烯、芴、苊、?、苯并(a)蒽进行定性分析,并与3个标准中的出峰顺序进行比较。结果苊烯、苊、芴、苯并(a)蒽、?的出峰时间分别为6.450、7.923、8.233、17.760、18.740min,与标准HJ478-2009﹑HJ647-2013的出峰顺序存在差异。结论在使用标准HJ478-2009﹑HJ647-2013、HJ 784-2016同时测定16种多环芳烃时,多环芳烃的出峰顺序及时间应以HJ 784-2016为准。

| Abstract: | By comparing the peaking sequence of polycyclic aromatic hydrocarbons (PAHs) determined by high performance liquid chromatography (HPLC) in environmental standards, it was found that the peaking sequence between HJ478, HJ647 and HJ784 was contradictory, which affected the judgement of the detectors and the correctness of the data. In order to guide the experimenters to produce the correct test results, the correct time and sequence of different substances in the peak order of polycyclic aromatic hydrocarbons (PAHs) in high performance liquid chromatography (HPLC) were determined by single-label experiments. |
