摘　　要：　　利用高分辨气相色谱-低分辨质谱(HRGC-LRMS)测定了某垃圾焚烧厂布袋飞灰中的二噁英类物质,结果表明对于测定二噁英类浓度相对较高的垃圾飞灰而言,采用HRGC-LRMS是一种可行的方法,回收率在74%～114%之间.……The levels of PCDD/Fs in fly ash from municipal solid waste incinerator were determined by high resolution gas chromatography coupled to low resolution mass spectrometry (HRGC - LRMS) . The results show the method for determination of PCDD/Fs in higher concentrations samples by HRGC - LRMS was reliable. The 13C isotope internal standard recovery was 76% - 114% . The major species were PCDDs. The ratio of PCDDs/PCDFs was 4.6. The total concentration of PCDD/Fs was 211.7 ng/g, which was 0.69 ng I - TEQ/g.
