- 中文摘要: The microphase adsorption-spectral correction (MPASC) technique was described and applied to study the interaction of bromo-pyrogallol red (BPR) with cetyl trimethylammonium bromide (CTAB). The synergism mechanism of micelles was analyzed and discussed. The large electrostatic micelle adsorbs the chromophore in only the monolayer, and the adsorption obeys the Langmuir adsorption. The formation of the (BPR2‧CTAB)78 aggregate accelerates the Mo-BPR complex reaction. Experimental results showed the adsorption constant of the adsorption aggregate 6.20 ’ 105 and its molar absorptivity er610nm = 1.40 ’ 106 lmol-1cm-1. For analysis of samples, the recovery of Mo was between 97.4 and 107% and the RSD was less than 4.39%.
