表面活性剂溶液预胶束的形成及其聚集数的测定

本工作利用不同荧不探针研究SLS溶液中预胶束的形成,并采用动态和稳态的荧光衰变和猝灭的方法对SLS预胶束的分子聚集数 作了测定.还研究了在大于cpc条件下不同SLS浓度时、芘荧光精细结构中I~1/I~3的比值.提出在预胶束形成后,随SLS浓度变化,预胶束的结构也会不断地发生变化.

Premicello formation in surfactant solution and measurement of its average aggregation number

Premicelle formation in SDS solns. was studied by using a pyrene fluorescence probe method. Both dynamic and static fluorescence quenching methods were used to measure premicelle aggregation nos. Pyrene fluorescence fine structure intensity ratios measured at different SDS concns. indicate that premicelle composition and structure changes as SDS concentration changes.
