Abstract In this study, the adsorption of 5-Chlorouracil (5-ClU) on natural montmorillonite from Anatolia was investigated using FT-IR and Raman spectroscopy. The 5-ClU is a thymine antagonist and has some antitumor properties. The comparison of the vibrational spectra of the adsorbed 5-ClU with those of the free molecule provided data on the nature and characteristics of the clay organic complexes. The intercalation of 5-ClU within montmorillonite has been shown by X-ray diffraction to increase the interlayer spacing. Vibrational spectroscopy indicates that adsorbed 5-ClU molecules on montmorillonite are coordinated to exchangeable cations, directly or indirectly through water bridges.

5-氯尿嘧啶在蒙脱石上的吸附研究：红外和拉曼光谱研究

摘要 在本研究中，使用傅立叶变换红外光谱和拉曼光谱研究了 5-氯尿嘧啶 (5-ClU) 在来自安纳托利亚的天然蒙脱石上的吸附。5-ClU 是一种胸腺嘧啶拮抗剂，具有一些抗肿瘤特性。吸附的 5-ClU 的振动光谱与游离分子的振动光谱的比较提供了有关粘土有机配合物的性质和特征的数据。X 射线衍射表明 5-ClU 在蒙脱石中的嵌入增加了层间距。振动光谱表明吸附在蒙脱石上的 5-ClU 分子直接或间接通过水桥与可交换的阳离子配位。
