The analytical chemistry of synthetic dyes
Our research in this area has been dedicated to the development of methods for purifying synthetic dyes for structure confirmation and toxicological studies. A variety of chromatographic, crystallographic, and spectrometric methods were developed and published for use by the color chemistry community (cf. Fig. 4). These methods also proved useful for characterizing complex mixtures and for correlating dye structure with choice of techniques to employ.
