在三乙醇胺存在下，１－（４－硝基苯基）－３－「４－（苯基偶氮）苯基」－三氮烯与溴化十六烷基三甲铵和阴离子表面活性剂形成红色配合物，其最大吸收位于５５０ｎｍ。

A spetrophotometric method for determination of anionic sufactants has been reported. It is based on the formation of red complex of 1(4nitrophenyl)3(4phenyl azophenyl) , cetyltrimethylammonium bromide and anionic surfactant in the presence of triethanolamine.The maximum absorption wavelength of the complex is at 550nm. The apparent molar absorptivities of sodium dodecyl benzene sulfonate, sodium dodecyl sulfonate and sodium dodecyl sulfate are 3.02104,2.13104 and 2.94104Lmol-1cm-1, respectively. Beer's law is obeyed in the range of 0 to 4.18mg/L for DBOSO3Na, 0 to 2.18mg/L for DOSO3Na, 0 to 3...
