摘　　要：用精氨酸对蒙脱石进行改性,对改性后的蒙脱石进行X射线衍射(XRD)、红外光谱(FT-IR)和热重(TGA)等分析表征,找到具有最优配比的精氨酸改性蒙脱石,将其负载5-氟尿嘧啶.结果表明:精氨酸确实插层进入钠基蒙脱石的层间,精氨酸改性蒙脱石的有机化程度最高可达到30.17%,且其对5-氟尿嘧啶的吸附率可达34.98%.Montmorillonite was modified with arginine,and arginine modified montmorillonite was characterized by X-ray diffraction(XRD),infrared spectroscopy(FT-IR)and thermogravimetry(TGA).The optimum amount of arginine-modified montmorillonite was loaded with 5-fluorouracil.The experimental results showed that arginine was intercalated into the interlayer of sodium montmorillonite.The highest degree of organic modification of arginine-modified montmorillonite was 30.17%,and its adsorption rate of 5-fluorouracil reached 34.98%.
