Left -- Critical micelle
concentration of cetyl pyridinium
bromide as a function of the composition of the water-ethylene glycol mixed solvent
system. Predicted values are shown by the continuous line. The experimental
data are from literature, based on emf measurements
(squares), conductivity measurements (circles), and surface tension measurements
(triangles). Right – Predicted dependence of
the weight-average aggregation number of cetyl pyridinium bromide micelles in the water-ethylene glycol
mixed solvent as a function of the total surfactant concentration. Results
for the solvent systems containing 0, 40, 80, and 100 wt % ethylene glycol
are presented. |
