摘要：
The microphase adsorption-spectral correction (MPASC) technique was described and applied to the study of the interaction of azocarmine B (ACB) with cetyl trimethylammonium bromide (CTAB). The synergism mechanism of CTAB was analyzed and discussed. The adsorption of ACB on CTAB at pH 9.2 obeys the Langmuir monolayer adsorption. The great electrostatic micellar aggregate (ACB-CTAB(3))(26) was formed, on which the Cu-ACB complex was formed rapidly in the aggregate formula (Cu-ACB-CTAB(3))(26). The adsorption constant of the CTAB-ACB aggregate and the stability constant of the Cu-ACB complex was determined to be 3.45 x 10(5) and 7.71 x 10(5), respectively. The analysis of the samples gave the satisfactory quantitative results. (C) 2002 Elsevier Science B.V. All rights reserved.
