摘要：

以二氯甲烷为萃取溶剂，采用微波辅助萃取技术萃取抗菌纺织品中的三氯生，建立了一种气相色谱-电子捕获检测器(GC-ECD)方法对纺织品中的三氯生进行了测定。 对于阳性样品，采用GC/MS技术进行确认。 该方法简单快速、灵敏度高，检出限为1 μg/kg(S/N=3)，回收率为90%~106%，RSD均小于6%。 采用该方法对市售的抗菌纺织品进行测定，结果显示，部分市售抗菌纺织品中含有高浓度的三氯生。

Abstract:

The determination of triclosan in antimicrobial textiles was established by a gas chromatography(GC) method coupled with an electron capture detector(ECD). As for the positive samples, GC/MS was used for the confirmation of triclosan. Triclosan in antimicrobial textiles was microwave-assisted extracted using dichloromethane as the extraction solvent. This method was rapid, accurate and sensitive. The detection limit was 1 μg/kg at the signal to noise ratio of 3(S/N=3). The recovery ratio varied from 90% to 106%, while the RSD was all less than 6%. Triclosan in commercially available antimicrobial textiles was analyzed using the established method, and the results showed that a large amount of triclosan existed in some commercially available antimicrobial textiles.

Key words: gas chromatography-electron capture detector, Microwave-assisted extraction, Antimicrobial textile, Triclosan
