摘要:
The magnetic Fe 3 O 4 nanoparticle was functionalized by covalently grafting amine group with (3-aminopropyl) trimethoxy silane, and the Fe 3 O 4 -NH 2 nanoparticle and the Fe 3 O 4 nanoparticle were characterized by Fourier transform infrared, and X-ray diffraction. And the results indicated the amine-group was immobilized successfully on the surface of Fe 3 O 4 . The adsorption behavior of uranium from aqueous solution by the Fe 3 O 4 nanoparticle and the Fe 3 O 4 -NH 2 nanoparticle was investigated using batch experiments. The pH of initial ...
