| 摘 要： | 选取超声提取法和索氏提取法,对淮北煤田主采煤层新鲜煤样中多环芳烃进行提取,并利用气相色谱-质谱联用仪对提取液中的多环芳烃进行定量分析,研究了不同方法对提取原煤中(US-EPA)优先控制的多环芳烃种类、质量分数和分布的影响。结果表明,在本实验条件下索氏提取法在提取原煤中多环芳烃能力上优于超声提取法。

| Abstract: | The samples collected from the fresh raw coals in Huaibei coalfield were extracted by Soxhlet extracting method and ultrasonic-assisted extraction method respectively.The extracted liquids were determined by GC-MS.And the concentrations of PAHs attented by USEPA were analyzed.The impact on the concentration and distribution of PAHs extracted by different extracting methods from raw coal were studied.The study results indicated that the ability of Soxhlet extraction method to extract PAHs from raw coal is better than that of ultrasonic extraction method under the experimental condition suggested in this paper. |
