Adsorption behaviour of oxyethylated anionic surfactants - 2. Adsorption kinetics

摘要

The adsorption kinetics of anionic surfactants containing one to three oxyethylene groups have been studied at the water/air interface by measuring the dynamic surface tensions using maximum bubble pressure and drop volume tensiometry. On the basis of a diffusion-controlled adsorption model the dynamic surface tensions are discussed. Quantitative interpretation was possible when the initial load of a bubble was considered and a non-equilibrium adsorption layer at extremely short adsorption limes was taken into consideration.
