| 摘 要： | The ternary interaction of naphthochrome green (NCG) with cetyltrimethylammoniumbromide (CTAB) and rare earths (REs: Yb, Dy, Er and Eu) has been investigated with the micmsurface adsorption-speca-al correction technique (MSASC). The aggregation of NCG on CTAB obeys the Langmuir isothermal adsorption. The enrichment of NCG on CTAB and the presence of NaCI sensitize the complexation between REs and NCG. Both the binary aggregate and the ternary complex were characterized in the presence and absence of NaCl at pH 8.30 at 20 and 40℃.
