摘　　要：建立了一种灵敏分析地坪涂料中苯胺类化合物的大气预浓缩-气相色谱质谱方法。该方法测定样品中苯胺类化合物的线性范围为50~5000 ng/g,检出限为1.8~2.5 ng/g,定量限为6.0~8.3 ng/g。该方法应用于实际地坪涂料中苯胺类化合物的检测,在低、高两个加标水平下的加标回收率为91.3%~106.7%,相对标准偏差(RSD,n=6)在11.6%内。相较于JG/T 481—2015检测方法,本方法更为灵敏,适用于地坪涂料中苯胺类化合物释放量的痕量检测。A sensitive method for the analysis of aniline compounds in floor coatings by atmospheric preconcentration-GC-MS was developed.The linear range of aniline compounds was 50~5000 ng/g,with the limit of detection 1.8~2.5 ng/g and the limit of quantification 6.0~8.3 ng/g.The method was applied to the detection of aniline compounds in actual floor coatings.The average recoveries at low and high spiking levels ranged from 91.3%to 106.7%,with the relative standard deviations(RSD)within 11.6%.Compared with JG/T 481—2015 method,this method is more sensitive and suitable for the trace detection of aniline compounds in floor coatings.
