Abstract
The peculiarities of sorption mechanism of phenole molecules by poly(vinyla lcohol) and poly(acrylamide) (PVA-PAA(N)) films are examined. An analytical model of absorption process based on diffusive character of penetration of phenole molecules in polymer film with the following spontaneous capturing by selftuning traps is proposed. The analytical results can be easy compar ed with experimental data obtained by spectrophotometry method. The compari son of theory and experiment gives the average value of resulting diffusion lenght of phenole molecule during " free " life-time </< similar to 10(-6) cm.
