Micellization and surface
properties of aqueous solution of binary mixtures of Tween-80 and bromide
cetiltrimethylammonium
Abstract
Mixed micelles formation and interfacial properties
of aqueous of binary mixtures of Tween-80 and bromide cetyltrimethylammonium
have been studied. The experimental results were analyzed applying the regular
solution theory (RST), which allows for calculation of the composition of mixed
monolayers and micelles as well as the excess free energy of adsorption and
micelles formation, corresponding to mutual interactions between surfactants in
mixed adsorbed film and micelle and interaction parameters bs, bm.
The synergism was observed in the micelle as at the aqueous solution/air
interface.
