Infrared and Raman Spectroscopic Analyses of Poly(allylamine) Adsorbed on CaA, NaX, NaY, and ZSM-5 Synthetic Zeolites

Abstract

The adsorptions of poly(allylamine) solution on CaA, NaX, NaY, and ZSM-5 zeolites have been investigated by using FT-IR and micro-Raman spectroscopies. Vibrational wavenumbers of poly(allylamine) adsorbed on the mentioned zeolites have been reported and the adsorption characteristics of zeolites with different cations and molecular sizes have been compared. The small shifts to the high or low-frequency regions in the position of vibration modes or the disappearance of the vibration bands show that there are interactions between poly(allylamine) and zeolites. By considering the obtained results, we can say that the adsorption source of polymer on the mentioned zeolites can withstand the interaction between the amine group of polymer and the silanol hydroxyl group on the surface of the zeolites.
