| Abstract: | 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%. |
