Abstract: The method for the determination triclosan in five major categories of textiles by liquid chromatography - tandem mass spectrometry (LC-MS/MS) was established, and 15 samples were randomly selected from the market for survey analysis. The method has good linear relationship in the range of 0.01-0.5 μ g/mL, linear equation is: y=3.5e4x-994, correlation coefficient was 0.9998, the determination of the lower limit was 0.025 mg/L, the average recovery rate was 85.6 - 107.2%, the relative standard deviation was less than 7%. Only 2 samples was detected in all samples, showed that in textiles had been add triclosan.

Key words: liquid chromatography-tandem mass spectrometry, triclosan, textiles, survey
