| Abstract: | The microsurface adsorption–spectral correction (MSASC) technique has been applied to investigate the interaction of alkali blue 6B (AB6B) with cetyltrimethylammonium bromide (CTAB). The aggregation of AB6B on CTAB obeys the Langmuir isothermal adsorption. The aggregate was characterized by MSASC. For the monomer aggregate AB6B2CTAB formed, its binding constant is calculated to be K = 3.01·105 and its molar absorptivity to be 2.45·106 liters·cm–1 at  = 690 nm. The adsorption has been used to carry out quantitative detection of cationic surfactant in samples. |
