    Swelling of Nafion in methanol-water-inorganic salt ternary mixtures

  • Original language description

    The anisotropic swelling of Nafion 112 foil in methanol-water-inorganic salt was examined by the optical method. Our results show that even small addition of inorganic salt into methanol-water mixture affects kinetics as well as the swelling equilibrium.The effect of inorganic salts LiCl, NaCl, KCl, CsCl, CaCl2, CdCl2, K2CO3, KNO3, NH4Cl, and AgNO3 was studied. Swelling kinetics of Nafion in ternary mixtures including salt show maximum suggesting that in the beginning stage of swelling the diffusion ofmethanol is faster than ion transport. The experimental data, presented in this work, allow us to assume that swelling of Nafion decreases with increasing ionic radius of cation.

    Botnání nafionu v ternárních směsích methanol-voda-anorganická sůl

  • Czech description

    Bylo zkoumáno anisotropní botnání iontoměničové membrány Nafion 112 v ternárních směsích methanol-voda-anorganická sůl. Výsledky ukazují, že již velmi malé množství přidané soli do roztoku methanol-voda ovlivňuje kinetiku i rovnováhu bobtnacího děje. Měření byla prováděna se solemi: LiCl, NaCl, KCl, CsCl, CaCl2, CdCl2, K2CO3, KNO3, NH4Cl, a AgNO3. Z výsledků dále vyplývá, že míra bobtnání Nafionu klesá s rostoucím iontovým poloměrem.
