| 中文摘要: |
| 用丙酮/正己烷 (1:1) 混合溶剂, 微波萃取法提取环境空气总悬浮颗粒物(TSP)中16 种多环芳烃组分, 各组分萃取率为66 % ~ 83 %, 萃取效果较好。高效液相色谱法二极管阵列检测器和荧光检测器串联可同时测出16 种多环芳烃组分。在二极管阵列检测器响应的组分检测限为2.5μg/L~ 5.0μg/L, 荧 光检测器响应的组分检测限为0.01μg/L~0.1μg/L。对25μg/L 16 种多环芳烃标液作精密度试验, 相对标准差均 < 5 %, 精密度好。取两个交通干线环境空气样品作T SP 中多 |

| Using Acetone/hexane(1 1) mixedsolventand microwaveextraction method, 16 kindsof PAHsin TSP in ambient air was extracted. Extraction rate was between 66% and 83%. With HPLC method,diodearray detectorand fluorescence detectorcan detect16 kindsof PAHsinthesametime. For diode array detector,thedetectionlimit was2.5μg/L~ 5.0μg/L,forfluorescencedetector, 0.01μg/L~ 0.1μg/L. To do precisiontest,relativestandard deviation wasless5%. Twosamples wasdetected, 12 kinds were detected. |
