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.
