摘要：

The 4-sulfonylcalix[6]arene modified Fe3O4 (MFS) was characterized by FT-IR, SEM, VSM, TGA, etc., which showed that its saturation magnetization was 64.99 emug−1 with the particle size 10–40nm. The maximum adsorption efficiency by MFS for 2.5mgL−1 U(VI) solution amounted to 94.39%, which was higher than that by Fe3O4 (65.22%) under its optimum adsorption conditions. The adsorption of MFS and Fe3O4 were both followed the pseudo-second order model and the Langmuir isotherm model. The Gibbs free energy change and enthalpy change revealed that t...
