Obiettivo Surfactant adsorption at a liquid interface is usually accompanied by a gradient of the interfacial tension. This gradient causes interfacial transport and a hydrodynamic field which then influences the adsorption kinetics. The coupling of convective diffusion and other adsorption mechanisms with hydrodynamic fields leads to complex theoretical models of the dynamic adsorption layer which makes the experimental examination of the resulting theories very important.The systematic experimental study of adsorption dynamics in the case of rising or growing bubbles and drops, and harmonically perturbed interfaces, will be performed and used for the evaluation of theoretical predictions. A scientific basis will be established for the optimisation of technological processes, such as water purification from colloid particles and surfactants, ionic surfactant separation by flotation, and more academic questions, such as the determination of dynamic surface tensions at the surface of growing drops and bubbles, the determination of dilational rheological properties by investigating oscillating drops or bubbles and other harmonically perturbed interfaces.The predicted electrostatic retardation of interfacial oscillations by soluble ionic surfactants, similar to that of insoluble surfactants, will be experimentally investigated. The fact that soluble ionic surfactants behave under certain conditions like insoluble ones, for example, with respect to stabilising thin films, foams or emulsions, will be discussed as a favourable prospect for new technological applications.
