建立了气相色谱-三重四极杆串联质谱检测环境空气中多环芳烃的方法,并利用同位素稀释法对多环芳烃进行了测定.将该方法应用于华南地区某大型石化企业周边环境空气中多环芳烃的检测,并与气相色谱-质谱方法进行了对比.结果表明,该方法的仪器检出限(0.01~0.15 μg/L)和定量限(0.03~ 1.5 μg/L)均优于气相色谱-质谱法(0.1~0.8 μg/L和0.3~3.5 μg/L),并有更好的灵敏度与选择性.当利用气相色谱-质谱作为检测手段时,回收率指示物氘代菲和进样内标六甲基苯均受到了杂质的严重干扰,影响了定量结果的准确性,而三重四极杆串联质谱很好地解决了这些问题.实际样品分析时,标准曲线中16种多环芳烃相对响应因子的相对标准偏差为2.60%~ 15.6%,氘代化合物的回收率为55.2%~82.3%,空白加标样品的回收率为98.9%~ 111%,平行样品的相对标准偏差为6.50%~ 18.4%,采样空白含量范围为未检出~44.3 pg/m3,实验室空白含量范围为未检出~36.5pg/m3.上述研究表明,分析环境空气中的多环芳烃时,气相色谱-三重四极杆串联质谱方法值得推广.
