Abstract 1. 1. The surface properties of l -α-dipalmitoyl lecithin monolayers spread on 0.15 M solutions of NaCl, KCl or LiCl were determined at 25°, 35° and 45°. Using as comparison the properties of dipalmitoyl lecithin monolayers at the air-water interface it was observed that the presence of ions in the subphase increases the area per molecule, the surface potential and the surface dipole moment per molecule in the order Na + > K + ≈ Li + > H 2 O ; the surface viscosity and the energy of… Expand
