英文摘要: 2-(9-Carbazole)-ethyl-chloroformate (CEOC), a novel pre-column fluorescence derivatization reagent, has been developed for the analysis of aromatic amines. Taking five monocyclic aromatic amines (o-toluidine, aniline, 3,4-dimethylaniline, N-ethyl-p-toluidine, and p-phenylenediamine) as testing compounds, derivatization conditions such as pH of borate buffer, reaction time and fluorescent tagging reagent concentration have been investigated. By a one-step procedure, CEOC reacts readily with the aromatic amines to form stable derivatives with excitation and emission wavelengths, respectively, at 293 and 360 nm. This derivatization reaction could be finished within 20 min even at room temperature. The peak shapes of the derivatized aromatic amines can be improved greatly without any addition of competition amines into the mobile phase. Furthermore, this method can offer excellent quantitative precision with high tolerance of the matrix of samples. (C) 2003 Elsevier B.V. All rights reserved.
