Study on the Extraction and Determination of Acetone Accelerant in Fire Residue Samples

对火灾现场残留物中的助燃剂丙酮的提取和测定方法进行了试验研究,定性分析的灵敏度为:检出限量6.15μg,最低浓度0.53mg·L^(-1)。定量分析的检出限1.58mg·L^(-1),线性范围4.5~58.0mg·L^(-1)。将方法应用于模拟样品残留物中的助燃剂丙酮的提取和测定,结果满意。

A new method is proposed for the extraction and determination of acetone accelerant in fire resi due samples. The quantitative detection limit for acetone is 1.58 μg·mL^-1; and the liner range of the determination is 4.5-58.0 μg·mL^-1. The qualitative analysis sensitivity is： the minimum concentration is 0.53 μg·mL^-1 ; and the detection limit is 6.15 μg. The application of the method to the extraction and determination of acetone accelerant in fire residue simulation samples shows satisfactory results.
