| 摘要 | Spinel-structured Li1.6Mn1.6O4 (LMO) has received wide attention as ion sieve for the recovery of lithium from aqueous lithium resources. In this work, the branched-like LMO particles were prepared via calcinating orthorhombic LiMnO2. After extracting of Li+ in hydrochloric acid, the branched-like H1.6Mn1.6O4 (HMO) was obtained. During the preparing process, the structure, morphologies of LMO and HMO were characterized by XRD and SEM. The results indicated that HMO maintained the spinel and ordered array structure, which was beneficial to the lithium uptake behavior. Compared to normal HMO nanoparticles, the Li+ adsorption capacity of HMO by order array branched-like structure can reach to 43.8 mg/g while rod-like was 35 mg/g (C-Li: 150 mg/L, pH 11, T: 25 degrees C). The adsorption behaviors were well simulated by the pseudo-second-order and the Langmuir models. The reusability of the HMO implies that the branched-like HMO is a potential adsorbent for Li+ recovery from aqueous lithium resources. |
