| 英文摘要 | The growing demand for rare-earth elements (REEs) has led to the development of sustainable methods and materials for separating and recovering these critical metals (CM). Herein, metal was incorporated into a covalent organic framework (COF) via the solvothermal method for selective capture and uptake of scandium. The incorporation of metals into hybrid magnetic COF@COF materials has not been studied for CM's selective capture or recovery. The hybrid metal incorporated (MI-COF@COF) material shows good stability, fast kinetic, excellent selectivity, high affinity, and an enhanced adsorption capacity for scandium uptake (294.1 mg g(- 1), corresponding to 99.6 % adsorption efficiency), and robust reusability. The regression coefficient of the pseudosecond-order model achieves a higher value (R-2 = 0.999) and an equilibrium capacity of 53.5 mg g(- 1) with 98.5 % adsorption efficiency within 5 min. Notably, scandium is effectively separated with an efficiency of 94.0 % from red mud-leached solution in the presence of interfering ions. Aside from scandium, incorporating other metals into hybrid materials paved the way for economically feasible metal incorporation for targeted selective capture. |
