文摘
- •
System sodium dehydrocholate – hexadecyltrimethylammonium bromide in aqueous medium.
- •
Nonideal and asymmetric behavior result from very different surfactant structures.
- •
Affinity of DHC− for HTAB micelles is stronger than that of HTA+ for NaDHC ones.
- •
Mixture composition with minimum total free energy has minimal ionization degree.
- •
EOMMM asymmetric for realistic analysis when surfactant structure is very different.
