| 中文摘要: |
| 建立了加速溶剂萃取-固相萃取净化-高效液相色谱测定土壤中16种多环芳烃的方法, 优化了试验条件。方法线性关系良好,16 种多环芳烃的检出限在0.412 ng/g ～ 3.974 ng/g之间, 空白加标试验的相对标准偏差在1.2% ～ 12.7% 之间, 基质加标回收率在60.4% ～126% 之间。实际样品的测定结果表明该方法分离效果好, 能够满足土壤分析的要求。 |

| A method wasestablished by high effectiveliquid chromatography determination of16 polycyclic aromatic hydrocarbonsin soilsamples with accelerated solventextraction purify coupled with solid-phase extrac tion cleanup afterdetectivecondition wasoptimized. Thelinearrelationsbetween absorption valueand each poly cyclic aromatic hydrocarbon massconcentration were good, and detection limits ranged from 0. 412 ng/g to3.974 ng/g. Therelativestandard deviationsofblank standard addition ranged from 1.2% to12.7%. The matrix spike recovery ranged from 60.4% to 126%. The resultsofactualsamplesdetermination show the methodhasgood effectofseparation and meetsthe demand ofsoilanalysis. |
