| Abstract: | The synthesis of new reagent 1-( 5-naphthol-7-sulfonic acid )-3-( 4-phenvlazophenyl) triazene(NASAPAPT) and the condition of its colour reaction with dodecyldimethylbenzylammonium bromide(DDMBAB), cetyltrimethylammonium, bromide(CTMAB), cetylpyridinium bromide(CPB) and tetradecylpyridinium bromide(TPB) were studied. The range for the determination and their apparent molar absorptivities were determined. The method for the spectropotometric determination of trace cationic surfactants(CTMAB, DDMBAB, CPB and TPB) was established. |
