Résumé

On étudie l'influence des cations compensateurs sur le spectre P.I.R. d'une vermiculite hydratée à deux couches. La définition d'un paramètre IR permet de quantifier cet effet. On conclue que l'énergie d'hydratation du cation est en relation avec la rigidité de la couche interfoliaire.

Abstract

Abstract

The influence of the interlayer cation on the near I.R. spectrum of a two-water layer vermiculite is studied. This effect can be quantified by the definition of a parameter IR. It has been shown that the cation hydration energy is related to the rigidity of the interlayer space.

Kurzreferat

Kurzreferat

Es wird der Einfluß des Zwischenschicht-Kations auf das nahe I.R. Spektrum eines Zweiwasserschicht-Vermiculits untersucht. Dieser Effekt kann durch Definition eines Parameters IR zahlenmäßig ausgedrückt werden. Es wurde erwiesen, daß die Kationenhydrationsenergie zu der Steifheit des Zwischenschichtraumes in Beziehung steht.

Resumen

Resumen

Se estudia la influencia del catión de interestratificación en el espectro próximo al infrarrojo de una vermiculita con dos capas de agua. Este efecto puede cuantificarse por la definición de un parámetro IR. Se ha demostrado que la energía de hidratación de los cationes guarda relación con la rigidez del espacio entre capas.
