ANALYSIS OF INTERMOLECULAR INTERACTIONS IN MIXED ADSORPTION LAYERS OF SURFACTANTS

摘要: The adsorption of the surfactants mixtures different chemical nature such as Triton X-100 and sodium hexadecyl sulfate at surface graphitized carbon black was studied. Using model phase separation (the Rubi–Rosen approach), composition mixed layers parameters interaction between surfactant molecules in were calculated. It found that are enriched with non-ionic X-100. The purpose work to study binary various on non-porous hydrophobic sorbent SAS ratio mixtures. The results calculations show layer GC is significantly from solution. value parameter χ indicates molecules, even a small its content solution (αTХ-100 = 0,2). With an increase ТХ-100 molar fraction 0,2 0,8 share increases approximately 1.5 times. Negative values βs indicate excessive attraction ions mixture components layers. An absolute αTХ-100 characterizes enhancement interactions layer. Thus, course experiments carried out for systems SHDS-ТХ-100, existence synergistic effect relation established. surface  active  substance   the  triton  X-100.
