摘要
采用固相萃取富集河水样品中15种多环芳烃(PAHs),并用高效液相色谱法测定,通过优化萃取条件和仪器条件,使该方法在10.0μg/L^500μg/L范围内线性良好,相关系数R2>0.99。方法检出限为3.70 ng/L^27.2 ng/L,标准溶液平行测定7次RSD在10%以内,空白水样的加标回收率为39.3%~109%。
A solid-phase extraction( SPE)-high performance liquid chromatography( HPLC) method has been developed for simultaneous determination of 15 PAHs in river water. By optimizing the extraction conditions and instrument parameters,the results showed good linearity in 10. 0 μg / L ~ 500 μg / L with the correlation coefficient R2> 0. 99. The detection limits of 15 PAHs were 3. 70 ng / L ~ 27. 2 ng / L. The recoveries of standard addition for real water samples ranged from 39. 3% to 109%. The relative standard deviations of 7 times parallel determination of standard solution were less than 10%.
