| description | To achieve rapid and highly efficient recovery of Li<sup>+</sup> from seawater, a series of H<sub>2</sub>TiO<sub>3</sub>/cellulose aerogels (HTO/CA) with a porous network were prepared by a simple and effective method. The as-prepared HTO/CA were characterized and their Li<sup>+</sup> adsorption performance was evaluated. The obtained results revealed that the maximum capacity of HTO/CA to adsorb Li<sup>+</sup> was 28.58 ± 0.71 mg g<sup>−1</sup>. The dynamic k<sub>2</sub> value indicated that the Li<sup>+</sup> adsorption rate of HTO/CA was nearly five times that of HTO powder. Furthermore, the aerogel retained extremely high Li<sup>+</sup> selectivity compared with Mg<sup>2+</sup>, Ca<sup>2+</sup>, K<sup>+</sup>, and Na<sup>+</sup>. After regeneration for five cycles, the HTO/CA retained a Li<sup>+</sup> adsorption capacity of 22.95 mg g<sup>−1</sup>. Moreover, the HTO/CA showed an excellent adsorption efficiency of 69.93% ± 0.04% and high selectivity to Li<sup>+</sup> in actual seawater. These findings confirm its potential as an adsorbent for recovering Li<sup>+</sup> from seawater. |
