| 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(口恶)英类物质,结果表明对于测定二(口恶)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。该飞灰样品中以二(口恶)英为主,呋喃的含量相对较低,二(口恶)英／呋喃值为4.6,二(口恶)英类物质总量为211.7ng／g,折算到毒性当量为0.69ngI-TEQ／g。

| Abstract: | 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. |
