| Abstract: |
| CoFe2O4 material was prepared by hydrothermal synthesis method, and influences of pH value, ratio of solid to liquid, time, temperature, and initial U(Ⅵ) concentration on U(Ⅵ) in CoFe2O4 adsorption solution were investigated. The material was characterized by SEM and mechanism of its removal of U(Ⅵ) was analyzed. The results show that CoFe2O4 has a very good removal effect on U(Ⅵ). The maximum adsorption capacity of U(Ⅵ) is 73.9 mg/g under the conditions including pH value of 5.5, ratio of solid to liquid of 0.3 g/L, reaction time of 120 min, and U(Ⅵ) solution concentration of 30 mg/L. |
