Summary:The kinetics of natural surface film adsorption were examined in the inland waters and shallow marine waters of the Baltic Sea under calm conditions in 2000-01. A mixed kinetic-diffusion model is used to express the adsorption dynamics, using analyses of the surface pressure-time plots at short and long adsorption time intervals. The calculated values of the effective relative diffusion coefficiency and energy barrier for adsorption are in agreement with data reported for model non-ionic surfactant solutions . The adsorption barrier is affected by wind speed, which increases the surface pressure of the natural film exposed to wind shear stress.
