Abstract

The surface pressure-area and the surface potential-area isotherms for monolayers of two dicarboxylic acid derivatives on an aqueous ammonium nitrate solution subphase were measured using a Langmuir film balance. The ionic strength of the substrate seems to have a strong influence on the compression behavior of the monolayer film. The interaction between the ions and the surfactant monolayers is dependent on the structure of the polar head groups and the concentration of the electrolyte. FTIR studies on Langmuir-Blodgett films of these surfactants suggest that the surfactant polar head groups are associated with the electrolyte ions probably through ion-pair formation or hydrogen bonding at the interface.
