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 was established by high effective liquid chromatography determination of 16 polycyclic aromatic hydrocarbons in soil samples with accelerated solvent extraction purify coupled with solid-phase extraction cleanup after detective condition was optimized. The linear relations between absorption value and each polycyclic aromatic hydrocarbon mass concentration were good, and detection limits ranged from 0. 412 ng/g to 3. 974 ng/g. The relative standard deviations of blank standard addition ranged from 1.2% to 12.7%. The matrix spike recovery ranged from 60.4% to 126%. The results of actual samples determination show the method has good effect of separation and meets the demand of soil analysis.
