摘要： The ternary interaction of naphthochrome green (NCG) with cetyltrimethylammonium bromide (CTAB) and rare earths (REs: Yb, Dy, Er and Eu) has been investigated with the microsurface adsorption–spectral correction technique (MSASC). The aggregation of NCG on CTAB obeys the Langmuir isothermal adsorption. The enrichment of NCG on CTAB and the presence of NaCl 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℃.

Abstract: The solubility of the three component system H3BO3–NaCl–MgCl2–H2O at 25 and 100oC has been measured. On the basis of the phase diagram constructed, the process technology of producing H3BO3 by hydrochloric acid decomposition from certain Ulexite in Tibet has been analyzed.
