Summary: | <p class="ArticleAnnotation">A quantum chemical analysis has been carried out of the equilibrium structure and energy parameters of hydrated Li<sup>+</sup>, Na<sup>+</sup>, and K<sup>+</sup> cations interacting with ionized silica surface by means of density functional theory method with extended basis set 6-31++G(d,p) and exchange-correlation functional B3LYP. The calculated adsorption energy values related to those cations reproduce the experimental adsorption row of alkali metal cations at pH = 10.</p> <p class="ArticleAnnotation"><strong>Key words:</strong> silica, alkali metal hydroxides, density functional theory.</p> |
