Abstract
A resonance light scattering(RLS) method for the determination of critical micelle concentration(CMC) of sodium dodecyl benzene sulfonate(SDBS) was proposed. Under room temperature, the RLS intensity of the SDBS system increased with increasing SDBS concentration. And when the concentration of SDBS approached CMC, the RLS intensity had increased sharply. The RLS peaks were appeared at 330 nm and 396 nm, respectively. The plot of the RLS intensity at 396 nm versus SDBS concentration was S-Curve. The concentration of SDBS at the intersection point of two tangents to S-curve was considered as SBDS CMC. This result was consistent with the results of the pyrene probe fluorescence spectrometry and electrical conductivity method. The influences of the concentration of Ca2+ on the aggregation behave of SDBS and SDBS-emulsion OP(OP) systems were studied by the RLS method. The results indicated that the mixed关键词
