摘要
基于硫酸介质中重铬酸钾氧化乙醇的反应,建立了火场残留无痕迹助燃剂乙醇的定性和定量分析方法。定性分析检出限量5μg,最低检出浓度0.20mg.L-1。定量分析的检出限1.22mg.L-1,线性范围为0.10~3.2000g.L-1。将方法用于火灾现场残留的乙醇分析,结果满意。
A method for the analysis of traceless inflammable alcohol residue remained in evidence samples of the fire scene was established. The method was based on the oxidation of alcohol with dichromate in sulfuric acid medium. Limit of qualitative detection was 5 g or lowest concentration of 0.20 mgL^(-1), limit of quantitative determination was 1.22 mgL^(-1). Linearity was in range of 0.10~3.200 0 gL^(-1). The method has been applied to the analysis of evidence samples with satisfactory results.
