报道了1-(5-萘酚-7-磺酸)-3-[4-(苯基偶氮)苯基]-三氮烯(NASAPAPT)的合成,研究了该试剂与阳离子表面活性剂溴化十二烷基二甲基苄铵(DDMBAB)、溴化十六烷基三甲铵(CTMAB)、溴化十六烷基吡啶(CPB)、溴化十四烷基吡啶(TPB)显色反应的条件.测定了显色反应的灵敏度,符合比尔定律的范围.建立了光度法测定微量阳离子表面活性剂的新方法.

The synthesis of new reagent 1-(5-naphthol-7-sulfonic acid)-3-(4-phenylazophenyl) 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 cation...
