Interaction
between nonpolar surfaces in solutions of the cationic and nonionic surfactant
mixtures
Abstract
The
interaction energy have been measured between hydrophobic silica particles in
aqueous solutions of cationic (dodecylpyridinium bromide) and nonionic (Triton
X-100) surfactants and their mixtures. The effect of synergism with respect to
interaction energy hydrophobic surfaces has been observed in mixed solutions.
The values of interaction parameters were calculated based on ROSEN model. The
chain-chain interactions between nonionic and cationic surfactants have been
proposed to be main reasons for the observed synergism.
