계면활성제를 완충용액에 섞어서 사용하는 미셀 모세관 전기영동법(micellar electrokinetic capillary chromatography, MECC)을 이용하여, 아조염료의 합성성분이면서 동시에 아조염료가 분해될 때 생성되는 H-acid modifier 혹은 2-naphthylamine-1,5-disulfonic acid 등의 디아조 성분에 대한 분석을 수행하고, 이 분리 결과를 Ion-Paring 메카니즘을 이용한 고성능 액체 크로마토그래피법과 비교하였다. 이 방법을 이용하여 Direct Blue 2, Direct Blue 6, Direct Blue 15 등의 직접염료 그리고 Reactive Orange 4와 같은 반응성 염료의 혼합용액을 완전히 분리할 수 있었다. 특히 각 염료의 환원용액을 H-acid, J-acid,
Well known environmental wastes from dye industry were separated by the micellar electrokinetic capillary chromatography(MECC). These wastes include H-acid modifier and 2-naphthylamine-1,5-disulfonic acid, and are known to be the diazo components of the azo dye. The results of the separation were compared with the result obtained by the HPLC using ion-pairing mechnism. MECC method was also applied to separate a few direct dyes including Direct Blue 2, Direct Blue 6 and Direct Blue 15, and reactive dye such as Reactive Orange 4. Informations about the diazo components of any azo dye could be obtained by comparison of electropherogram of the reduction solution of given dye with those obtained from standard materials such as H-acid, J-acid,
