It is shown that both synergistic and antagonistic effects are observed upon the adsorption of cationic and nonionic surfactants from the mixed solutions. The compositions of mixed adsorption layers and the parameters of intermolecular interaction between surfactants of different natures are calculated. A possible mechanism is proposed for the adsorption process.enadsorptionsurfactantparaffinArticle
