Abstract

The migration velocities of surfactants on the surface of tap water are measured by the tracer method. The results are well reproducible, although the surfactants and the water are used without special purification. A decrease in the surfactant migration velocity with time was observed. It is found that the main cause of the decrease is an increase in the weight of the water adjacent to the surface film. The radial migration after a very short time is characterized by uniform surfactant motion.
