摘　　要：采用填充有表面涂渍2，4-二硝基苯肼（DNPH）的硅胶吸附管采集汽车内空气中的醛酮类羰基化合物，经乙腈洗脱定容，洗脱液采用高效液相色谱．紫外检测器（HPLC／UV）分析检测。该方法平行样品的相对标准偏差〈10％，回收率为95％～105％，检出限为1．6～7．1μg/m^3。方法适用于车内环境中醛酮类羰基化合物的分析测试。Silica gel cartridge coating 2,4-dinitrophenylhydrazine （DNPH） was used to collect aldehydes and ketones in car microenvironment air. The sampled cartridges were extracted with acetonitrile, and the DNPH derivatives of aldehydes and ketones analysis was completed by high performance liquid chromatography. The relative standard deviation of duplicate samples was less than 10%, recoveries of the compounds were between 95% and 105%, and the detection limits were 1.6-7.1 μg/m^3. The results shows that this method can be used for quantitative analysis of aldehydes and ketones in car microenvironment air.
