摘　　要：采用表面解吸常压化学电离质谱法（DAPCI—MS），建立了一种能直接对棉布等纺织品表面8种致癌芳香胺快速进行定性定量检测的方法。实验结果表明，在无需样品预处理的情况下，方法仍然能够保持相对较高的灵敏度，检出限0．02～O．58pg／mm^2，相对标准偏差1．8％-4．3％，回收率78．4％～90．7％。单个样品的检测时间不超过30S。DAPCI—MS技术适合分析各种材料表面，包括丝绸、麻、羊毛以及各种化纤制品。：Surface desorption atmospheric pressure chemical ionization mass spectrometry （DAPCI-MS） was employed for fast detection of 8 carcinogenic aromatic amines on the surface of textile, without any sample pretreatment. Results show that relatively high sensitivity has been obtained in the present study, even though no sample pretreatment were carried out. Low limits of detection （ LOD = 0. 02 - 0. 58 pg/mm2 ）, acceptable relative standard deviation （ RSD = 1.8% - 4. 3% ）, and reasonable recoveries （ 78.4% - 90. 7% ） were achieved with this method for direct detection of 8 carcinogenic aromatic amines on the highly rough surface of textile. The average analysis time for each single sample was less than 30 seconds. DAPCI-MS is proved to be a useful tool for rapid detection of aromatic amines on the highly rough surface of various types of textile materials, which are composed of silk, hemp, wool, etc. , respectively. Due to the advantages of minimal sample procedure, easy operation, and nondestructive test, the method developed here has promising applications for online quality monitoring of carcinogenic aromatic amines on the surface of textiles.
