METHOD OF THE GREEN-FUNCTIONS IN THE KINETICS OF ADSORPTION FROM MICELLAR SURFACTANT SOLUTIONS

The kinetics of adsorption from micellar surfactant solutions is consi dered theoretically from a uniform point of view. Three boundary value problems for the adsorption on flat and on spherical interface are so lved analytically by means of the method of the Green functions. In th is way the bulk concentration and the adsorption of surfactant monomer s are expressed as functions of time. The contribution of the micelles (surfactant aggregates) to the diffusion of the monomers is accounted for as pseudo-first order reaction. The adsorption from surfactant so lutions without micelles turns out to be the particular case of the pr oblems considered here. Being general in form, the derived equations c an be applied also to other practical problems in heterogeneous chemic al kinetics, adsorption of gases, heat transfer, etc.
