Determination of Aromatic Amines in Textile After Bromination, by Gas Chromatography Coupled with Electron Capture Detection

A new analytical method is developed for the improved determination of banned aromatic amines in textiles based on the bromination of the aromatic ring system to yield the corresponding bromo derivatives. The derivatization method is very easy to perform and the derivatives can easily extract and separate with gas chromatography. Due to the introduction of the electron withdrawing bromo substituents sensitive detection with very low limits of detection using an electron capture detector is possible. The method was optimized and used for the analysis of textile with quantitative recoveries from spiked samples.
