高效液相色谱法分析地下水和饮用水中苯并(a)芘

Determination of Benzo pyrene in Groundwater and Drinking Water Samples by High Performance Liquid Chromatography

摘要: 采用液-液萃取、高效液相色谱法测定地下水和饮用水中的苯并(a)芘,建立了适用于全国地下水污染调查项目多环芳烃中苯并(a)芘必测组分的检测方法。标准曲线的线性范围为2.00~80.0 ng/L,相关系数为0.9999,方法检出限为1.8 ng/L,回收率为93.1%~103.2%,相对标准偏差(RSD,n=7)为6.48%。方法检出限低,精密度好。

Abstract: A method for the determination of Benzo pyrene in groundwater and drinking water samples from China Groundwater Survey Project by high performance liquid chromatography was developed. The linear range of the calibration curves was from 2.00 to 80.0 ng/L with correlation coefficient of 0.9999. The detection limit of the method was 1.8 ng/L and the recoveries were 93.1%~103.2% with precision of 6.48%RSD (n=7). The method provides the advantages of low detection limit and high precision.
