| Description
| - The paper presents the determination of mobility of H3O+ and NO3- ions and diffusivity of the non-dissociated form of acid on the basis of experiments with nitric acid carried out in a batch mixed cell with an anion-exchange membrane NEOSEPTA-AFN, which have been completed by measurements of membrane conductivity. The dependencies of mobility of H3O+ and NO3- ions upon the acid concentration in the membrane were approximated by the second degree polynomial, whose coefficients were determined by the numerical integration of the differential equation describing the time dependence of nitric acid in the cell followed by an optimizing procedure. Diffusivity of the non-dissociated form was calculated from mobilities of H3O+ and NO3- ions. The model used is based on the Nernst-Planck electro-diffusion equation and takes into account ionic equilibrium between the species. Using all the experimental data obtained at various acid concentrations and rotational speeds ofthe stirrers, it was found that the transp

- Clanek presentuje stanoveni mobility H3O+ a NO3? iontu a difuzivity nedisociovane formy kyseliny na zaklade experimentu provedenych ve vsadkove michane cele s anion-vymennou membranou Neoseta-AFN. Tyto experimenty byly doplneny o mereni vodivosti membrany. Zavislosti mobilit H3O+ a NO3? iontu na koncentraci kyseliny v membrane byly aproximovany polynomem druheho stupne, jehoz koeficienty byly urceny numerickou integraci zakladni diferencialni rovnice popisujici casovou zavislost koncentrace kyseliny dusicne v cele s naslednou optimalizaci. Difuzivita nedisociovane formy pak byla vypoctena z mobilit H3O+ a NO3? iontu. Pouzity matematicky model je zalozen na Nernst?Planckove elektro-difuzni rovnici a respektuje iontovou rovnovahu. S pouzitim vsech experimentalnich dat ziskanych pri ruznych koncentracich kyseliny a frekvencich otaceni michadel bylo zjisteno, ze transportni charakteristiky uvedene vyse (s vyjimkou mobility NO3? iontu) jsou ovlivňovany koncentraci kyseliny dusicne v membrane.
