摘要
建立了加速溶剂萃取法(ASE)萃取-凝胶渗透色谱(GPC)净化-气相色谱-质谱法(GC/MS)测定焚烧炉废弃物中14种多氯联苯(PCBs)残留量的方法。结果表明,14种PCBs在10~500μg/L范围内呈良好的线性关系,相关系数R2≥0.999 7,检出限在1.5~5.0μg/kg之间;回收率为86.2%~98.7%,相对标准偏差(RSD)为1.1%~3.9%。该方法具有操作简便、检出限低、准确度高等优点。
A method for determination of 14 kinds of PCBs（ PCBs） residue amount in incinerator waste by accelerated solvent extraction（ ASE） extraction,gel permeation chromatography（ GPC） purification and gas chromatography-mass spectrometry（ GC/MS） is established. The results show that the 14 PCBs displays good linear relationships in the range of 10 g/L to 500 g/L with correlation coefficient R2 not less than 0. 999 7; the detection limits are ranged from 1. 5 μg/kg to 5 μg/kg; the recovery rate are between 86. 2% and 98. 7%,the relative standard deviation（ RSD） is ranged from 1. 1% to 3. 9%. The method has the advantages of simple operation,low detection limit and high accuracy.
