| Popis: | The peculiarities of sorption mechanism of phenole molecules by poly(vinylalcohol) 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 compared with experimental data obtained by spectrophotometry method. The comparison of theory and experiment gives the average value of resulting diffusion lenght of phenole molecule during «free» life-time ∼10 -6 cm. |
