Abstract

The interaction between sodium atoms (obtained by thermal decomposition of NaN3) and acidic OH groups of the zeolite framework has been investigated by IR spectroscopy. Reduction in band intensities could be observed, its extent depending on the amount of NaN3 and temperature. Impregnated samples showed displacement of the N=N≡N⊖ IR band characteristic of salt occlusion.

Abstract

Взаимодействие между атомами натрия, полученными тепмическим разложением NaN3, и кислыми группами OH скелеита было исследовано с помощыо ИКспектороскопии. наблйдалось уменьшение интенсивности полосы со степыeнью, зависящей от количества NaN3 и темпаратуры. Для импрегнированных полос наблюдалось N=N≡N−, характерной для окклюзии соли.
