Description
  • Byla studována adsorpce cetylpyridinia (CP) a cetyltrimethylammonia (CTA) na sodném montmorillonitu (MMT). Molekulární modelování bylo provedeno v programu Cerius2. Alkylové řetězce byly orientovány do různých poloh vzhledem silikátovému povrchu. 55 molekul vody a 17 molekul ethanolu bylo umístěni v různých vzdálenostech od povrchu MMT. Výsledky ukazují, že interakce mezi CTA a MMT jsou slabší než mezi CP a MMT. Tyto závěry byly potvrzeny i experimentálně sestrojením adsorpčních izoterem pro oba kationty. (cs)
  • Adsorption of cetylpyridinium (CP) cations and cetyltrimethylammonium (CTA) cations on Na-montmorillonite (MMT) was studied. The molecular modelling was calculated in Cerius2. Alkyl chains were placed in different positions (parallel, perpendicular, tilted) with respect to a silicate layer. . A bulk of 55 water and 17 ethanol molecules was placed into these models with different distances from the silicate layer. The results showed that the interaction energies between CTA and the MMT surface are lower than for CP.
