Abstract: Abstract: The mechanism of diffusion of analyte molecules in polymer films is studied. Equations in partial derivatives are derived for the description of both diffusion and adsorption of molecules in the polymer film containing sites of specific absorption. The kinetic parameters that characterize the specificity of adsorption sites are established. A theoretical approach is applied for the analysis of the experimental data on the diffusion of some volatile organic compounds in films based on molecularly imprinted polymers
