【摘要】 本文研究了有机溶剂加入后,表面活性剂增敏型体系微环境的变化。用核磁共振方法确定了有机溶剂分子与CTMAB胶束分子的作用部位。通过CTMAB溶液电导率测定及c.m.c值的测定,发现有机溶剂加入确实形成了一种新胶束。还研究了有机溶剂对显色反应速度的影响。并考察了体系微环境变化与相应显色液吸光度值的关系。我们的实验初步表明,有机溶剂的存在,改变了原有的CTMAB胶束,是增敏作用的重要因素,因而改变了发生显色反应的微环境。更多还原

【Abstract】 The effects of organic solvents on the mieroenvironments of colour reactions have been described in detail. The possible area of effect between CTMAB micellar and acetone has been studied using 90 Q NMR method. The organic solvent may change the microenvironments of colour reaction systems and electrical conductivity. Moreover, some characteristics of colour reactions just as the change of colour reagent’s PK_a the rate of M-CAS-CTMAB may be influenced by organic solvent solvation. Our results verify that the solvation of organic solvent plays important effect on the surfactant-sensitizing complex systems.更多还原
