| 中文摘要: |
| 采用超声提取、固相萃取法处理土壤，用超高效液相色谱-电喷雾串联三重四极杆质谱测定样品中11种全氟化合物，通过优化测定条件，使方法在0.100 μg/L~150 μg/L范围内线性良好(r2>0.995)。当取样量为2.0 g时，方法检出限为0.1 ng/g~0.4 ng/g。实际土壤样品的加标回收率为67.2%~106%，测定6次结果的RSD为6.6%~17.3%。 |
| 英文摘要: |
| A method for the determination of 11 perfluorinated compounds in soil was established by ultrasonic extraction, solid phase extraction and ultra high performance liquid chromatography coupled with electrospray ionization tandem mass spectrometry (UPLC ESI MS/MS). The results showed that good linearity of 11 target compounds was obtained in the range of 0.100 μg/L~150 μg/L with correlation coefficients (r2) greater than 0.995. The limits of detection(LODs) were 0.1 ng/g~0.4 ng/g when the sampling weight was 2.0 g. The recoveries ratio of soil samples were 67.2%~106%, and the relative standard deviations (RSDs) were 6.6%~17.3%. |
