The steady-state fluorescence quenching method was used to determine the aggregation number of bound-micelle (Nb) of sodium dodecyl sulfate (SDS) in the ternary mixing system of alkali metal (Li, Na or K) sulfate-SDS-polyethylene glycol (PEG).
采用稳态荧光猝灭技术测定了三种碱金属(Li,Na或K)硫酸盐-SDS-PEG三元体系中SDS(十二烷基硫酸钠)的束缚胶束聚集数Nb,考察了SDS浓度c、碱金属硫酸盐浓度ce及PEG(聚乙二醇)浓度cp变化时SDS的Nb的变化规律。
The correlations between the micelle aggregation number(Nm),the viscosity(η),and equili-brium concentration of SDS monomer(cUF) in the solution were studied by means of surface tension determination,steady-state fluorescence quenching,ultra-filtration,and viscosity analysis.
实验条件下,不同浓度的十二烷基硫酸钠(SDS)浓溶液与/不与氯化钠共存时,对应于不同SDS浓度区域和相应的不同胶束形状时,胶束聚集数Nm、溶液本体的平衡单体浓度cUF及粘度η三者间有明显的相关性。
The properties of surface chemistry and micellar aggregation number (Nm) of a special anionic surfactant with two hydrophilic head groups linked by a rigid structure- disodium hexadecyl diphenyl ether disulfonate (C16-MADS) was determined respectively.
