表面活性剂SDS/TX-100混合体系的NMR研究
Mixed Micelles of Sodium Dodecyl Sulfate and Triton X-100 in Aqueous Solution Studied by 1H NMR
摘要
Abstract
1H chemical shifts of sodium dodecyl sulfate (SDS) and Triton X-100 (TX-100) were measured in their mixed aqueous solutions with different molar ratios. The critical micelle concentrations (cmc_1~*, cmc_2~*) of the two surfacents and the critical mixed micelle concentrations (cmc~*) at different molar ratios were calculated by simulating the chemical shift data using a two-state exchange model. The interaction parameters (βM) and the composition of mixed micelles were evaluated. The mixed-micellization processes were discussed on the basis of the results obtained.关键词
