The last-mentioned variable can be used to help determine the adsorption coefficient from measurements made with a bubble pressure tensiometer. Measurement The CMC is determined with a tensiometer by measuring the surface tension of a concentration series. With pure surfactants, the SFT is linearly ...
(CMC) of each mixture, and that 25/75 mol% GML/LA micelles exhibited the greatest degree of vesicle rupture activity with ~100% efficiency that exceeded the rupture activity of other tested mixtures, individual compounds, and past reported values with industrial surfactants. Importantly, 25/75 ...
CMC(临界胶束浓度)是指在一个体相中 表面活性剂超过一定浓度其分子开始聚集形成胶束的浓度,临界胶束浓度是表面活性剂的一个重要参数。背景 表面活性剂浓度增加时,在表面上发生吸附过程直到被完全覆盖,此时对应表面张力(SFT)最小值,胶束于超过临界胶束浓度时在体相中开始形成。
The surface excess concentration can be calculated when measuring the CMC from the slope of the concentration-dependent region of the surface tension based on the equation given above. The result can be combined with results from bubble pressure tensiometer measurements in order to determine the adsor...
The surface excess concentration Γ is the area-related concentration of a surfactant at the surface or interface. It has the unit mol/m2.
