- 中文摘要: The microsurface adsorption-spectral correction technique and light adsorption ratio variation approach were jointly applied to characterization of the interaction of reactive brilliant red (RBR) with cetylpyridinium chloride (CPC) at pH 3.67. The interaction responded with the Langmuir isothermal adsorption. The saturated binding ratio of RBR to CPC is (1.2 ± 0.1): 1, and the bind constant of the RBR-CPC complex was calculated to be (1.15 ± 0.05) ’ 105 l/mol. The interaction was applied to the determination of cationic surfactant in water by the light adsorption ratio variation approach with satisfactory results.
