摘　　要：利用固相萃取膜富集,气相色谱-离子阱质谱联用法测定水中17种多环芳烃。通过实验表明,该方法操作简便,灵敏度高,精密度好,采用气质联用技术,内标法测定,定性、定量准确。用该方法测定实际样品,平均回收率为80%～113%,17种多环芳烃的方法检出限为0.07～0.23μg/L。The method used liquid-solid disk extraction and gas chromatography/ion trap mass spectrometry to analyze 17 compounds of PAHs in water. The study proved the method was user-friendly, high sensitivity and accurate for PAHs determination of water samples by using GC/MS and the internal standard method for identification and quantitative analysis. The average recoveries of PAHs in samples were between 80 % and 113 %, the MDL of 17 PAHs were 0.07-0.23 μg/L.
