| Description
| - Sorpce par organických rozpouštědel v amorfním teflonu AF2400 byla studována v širokém rozmezí aktivit par při 25C pomocí gravimetrické metody. Sorpční izotermy hexanu, toluenu a chloroformu vykazovaly konkávní závislost na tlaku a bylo možné je popsat modelem duální sorpce. Parametry modelu byly korelovány se čtvercem kritické teploty a vykazovaly lineární závislost. Třetí parametr, tzv. Lagmuirova sorpční kapacita, klesal s rostoucím kritickým objemem rozpouštědel. Sorpční izotermy metanolu a etanolu měly s tlakem konvexní charakter a získaná data jsou v souladu s teorií tvorby tzv. clusterů (shluků) v silně hydrofobním polymeru. Koncentračně závislý difuzní koeficient byl stanoven ze sorpční kinetiky. (cs)
- Vapor sorption in amorphous Teflon AF2400 of various organic solutes was studied in a wide range of activity at 25 C by means of the gravimetric technique. The sorption isotherms of hexane, toluene and chloroform were shown to be concave to the pressure axis and are consistent with the dual mode sorption model (DMS). The parameters of the DMS model kD and b reveal a linear correlation with squared critical temperature of solutes Tc2. The third model parameter, the Langmuir sorption capacity CH decreases when the critical volume of solutes increases. Sorption isotherms of methanol and ethanol were shown to be convex to the pressure axis and are consistent with cluster formation in strongly hydrophobic polymer. Concentration-dependent diffusion coefficient D were determined using a linear implicit difference scheme in analysis of sorption kinetics.
