| 摘 要： | 在碘的水溶液和I-3溶液2种体系中测定了十二烷基硫酸钠(SDS)的临界胶束浓度(CMC),讨论了在I-3体系中,不同硫酸钠和氯化钾对测定结果的影响,在碘的水溶液中研究了不同碘浓度对SDS的CMC的影响。采用分光光度法求得SDS在两种体系中的CMC值,硫酸钠与氯化钾对CMC的值有影响,且硫酸钠对SDS的表面活性影响大于氯化钾;在碘的水溶液中,随碘的浓度增大,CMC呈增大趋势。

| Abstract: | Critical micelle concentrations(CMC) of sodium dodecyl sulfate(SDS) in aqueous solution of iodine and I-3 solution were determined,and two salts,sodium sulfate and potassium chloride on the impact of CMC of SDS in the aqueous solution of iodine in different concentrations of iodine were also discussed.The CMC of SDS obtained in two different systems are different by using spectrophotometry.Sodium sulfate salts on the impact of the surface activity of SDS are greater than potassium chloride in I-3 solution,a... |
