S. Borros et al., The use of capillary electrophoresis to study the formation of carcinogenic aryl amines in azo dyes, DYE PIGMENT, 43(3), 1999, pp. 189-196
A capillary zone electrophoresis (CZE) method for separating and detecting
certain aromatic amines is described. In this study, the utility of this te
chnique for monitoring dyes syntheses is also demonstrated. In addition to
the analysis of amines, CZE can detect other impurities present in the star
ting materials used in dye synthesis. The influence of reaction conditions
on the amount of carcinogenic amines liberated from azo dyes following sodi
um dithionite treatment is discussed. (C) 1999 Elsevier Science Ltd. All ri
