Investigation Of Adsorption Of 5-Bromouracil From Aqueous Solutions To Montmorillonite And Its Interaction With Clay Framework: A Ft-Ir Spectroscopic Study

Abstract

Adsorption of 5-bromouracil molecules onto montmorillonite was studied by FT-IR spectrometry. 5-Bromouracil, a thymine antagonist, is used to treat inflammatory tissues. The intercalation of 5-bromouracil within montmorillonite has been shown by X-ray diffraction to increase the interlayer spacing. The results indicate that sorbed 5-bromouracil molecules on montmorillonite are coordinated to exchangeable cations indirectly through water bridges.
