15,26-diyl) dibenzenesulphonate [BSC14-C6-14CSB] and sodium 4,4′-(18,27-dioxo-17,19,26,28-tetraaza-tetracontane15,26-diyl) dibenzenesulphonate [BSC16-C6-16CSB]) with conventional anionic surfactant (sodium dodecyl sulphate [SDS]) by conductivity and fluorometry methods. The conductivity measurements were done over a range of mole fractions of SDS at different temperatures to study the mixed micellization
在这里,我们显示了阴离子苯磺酸盐(即4,4'-(16,25-dioxo-15,17,24,26-四氮杂-六三aco烷15,26-二基)钠)二苯磺酸盐之间的混合胶束形成[BSC14- C6-14CSB]和4,4'-(18,27-dioxo-17,19,26,28-四氮杂-四contane15,26-二基)二苯磺酸钠[BSC16-C6-16CSB])与常规的阴离子表面活性剂(十二烷基钠)硫酸盐[SDS])通过电导和荧光法测定。在不同温度下,在一定范围内的SDS摩尔分数下进行电导率测量,以研究混合的胶束化和热力学参数,而在SDS的整个摩尔分数范围内进行荧光测量,以观察聚集和微极性。电导研究证实了在所有温度下SDS与[BSC14-C6-14CSB]和[BSC16-C6-16CSB]在所有摩尔分数中的协同作用。采用Rubinghs正解理论(RST)评估胶束摩尔分数,X 1,是混合胶束系统和吉布斯过量自由能(G
