The process of the reduction of azo dyes used in dyeing textiles on the basis of infrared spectroscopy analysis

Nowadays the world observes a widespread campaign against the use in yam of dangerous, carcinogenic amines which penetrate human organisms. Their sour ce in organisms is the process of biological reduction of azo dyes which ar e used in dyeing yam. The current obligatory methods of aromatic amine iden tification are the widely understood chromatographic methods. In this work, the identification of amines through the fourier transform infrared spectr oscopy has been suggested. The results of the experiments have allowed the use of the same method in aromatic amine identification. (C) 1999 Elsevier Science B.V. All rights reserved.
