| Description
| - The transport of sulfuric acid through an anion-exchange membrane Neosepta-AMH (Tokuyama Soda, Co., Inc.) has been studied. For that purpose, a two-compartment batch cell with stirrers has been used. The experiments have been carried out at various initial acid concentrations and intensity of mixing in both the compartments, the temperature being kept at a constant value of 20°C. The time dependences of the acid concentration, which have been recorded, have enabled the calculation of apparent diffusivity of sulfuric acid. The dependence of apparent diffusivity upon its concentration has been approximated by the second degree polynomial whose coefficients have been determined with the help of the model based on the Fick?s law. Using all the experimental data obtained, it has been shown that apparent diffusivity of sulfuric acid in the membrane is strongly concentration-dependent. Moreover, it has been found that diffusivity of sulfuric acid in a Neosepta-AMH membrane is much lower than that in a Neosep

- Byl studován transport kyseliny sírové anion-výměnnou membránou Neosepta-AMH. K tomuto účelu bylo použito dvou-komorové vsádkové cely s míchadly. Experimenty byly prováděny při různých počátečních koncentracích kyseliny a různých intenzitách míchání ? teplota byla konstantní 20 °C. Zaznamenané časové závislosti koncentrace kyseliny sírové umožnily výpočet zdánlivé difuzivity kyseliny sírové. Závislost zdánlivé difuzivity kyseliny na její koncentraci v membráně byla aproximována polynomem druhého stupně a jeho koeficienty byly určeny pomocí modelu, který vycházel z Fickova zákonu. S použitím všech experimentálních dat bylo ukázáno, že zdánlivá difuzivita kyseliny sírové v membráně je značně závislá na koncentraci kyseliny. (cs)
