摘要
利用选择离子监测(SIM)检测苯并(a)芘的特征离子峰,建立了离子阱气相色谱质谱联用测定饮用水中苯并(a)芘的方法,苯并(a)芘的最小检出限为0.002ug/L.建立的方法灵敏度高、预处理简单、精密度高(4.7%～6.9%)、回收效果好(85.1%～100.8%),适宜用作水中的苯并(a)芘的定性定量检测.
A new method for determination of Benzo(a)Pyrene in water by ion-trap gas Chromatography/Mass was developed.The results indicated that the detected limit of Benzo(a)Pyrene was 0.002 μg/L. The proposed method was of high sensitivity, small relative standard deviation(4.7%-6.9%) and high recovery rate(85.1%100.8%) and suitable for qualitative and quantitative analysis of Benzo(a)Pyrene.
