Screen-Level Determination of PCDDFs in Flue Gases from Waste Incinerators by the Use of HRGC-QMS

  • 摘要: 建立并优化了应用HRGC-QMS(高分辨气相色谱-四极杆质谱)对废弃物焚烧设施排放废气中17种2,3,7,8-PCDD/Fs进行筛查测定的方法,并对其关键技术进行了研究. 结果表明,严格的样品净化程序和优化的仪器参数提高了低分辨质谱在二NFDA1英类定量分析中的准确性和精密度,仪器检出限为0.5~5 pg,方法检出限为0.9~20 pg,提取内标回收率符合二NFDA1英类分析要求. 利用该方法对57个废弃物焚烧设施排放的废气样品进行检测,得到的毒性当量(TEQ)浓度与高分辨磁质谱(标准分析仪器)的测定结果具有良好的线性关系(R2=0.978 5).
