| 中文摘要 |
| 建立了一种可变波长检测器(VWD)和荧光检测器(FLD)串联的高效液相色谱分析方法,检测了北京市某钢铁厂及其东门地区大气可吸入颗粒物PM2.5中的16种EPA优控多环芳烃(PAHs)污染情况.在设定的色谱条件下,这16种PAHs得到完全分离.其中前10种PAHs采用VWD检测,后6种PAHs采用FLD检测.16种PAHs的检测限在0.29μg·L-1(Bkf)～50.6μg·L-1(Nap)之间,回收率在85.1%(Nap)～103.2%(Fla)之间,相对标准偏差在4.31%(Flu)～9.93%(Ind)之间.结果表明,该地区多环芳烃污染情况仍然非常严重. |
| 英文摘要 |
| The paper describes the determination of the 16 polycyclic aromatic hydrocarbons(PAHs) prescribed by Environmental Protection Agency in PM2.5 in certain ironworks district of Beijing by HPLC.A HPLC method of VWDFLD connected in series was founded.The 16 PAHs were completely separated by the method.The earlier eluted ten PAHs were detected by VWD and the rest were detected by FLD.The minimum detection limits of the 16 PAHs vary from 0.29 μg·L-1(for Bkf) to 50.6μg·L-1)(for Nap),the average recoveries range between 85.1%(for Nap) and 103.2%(for Fla) and the relative standard deviations are between 4.31%(for Flu) and 9.93%(for Ind).The detection results indicate that the pollution situation is still very serious in this district. |
