“…Obviously, the Li + uptake of HMO‐1 (51.47 mg/g) and HMO‐2 (44.34 mg/g) at 50 °C was higher than that at 30 °C and 40 °C by the diffusion rate. These results indicate the L i+ adsorbed onto HMOs surface was an endothermic process …”

Spinel-structured Li 1.6 Mn 1.6 O 4 (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 LiMnO 2 . After extracting of Li + in hydrochloric acid, the branched-like H 1.6 Mn 1.6 O 4 (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°C). The adsorption behaviors were well simulated by the pseudo-second-order and the Langmuir models. The reusability of the HMO implies that the branchedlike HMO is a potential adsorbent for Li + recovery from aqueous lithium resources.

“…The maximum of Li + adsorption capacity ( q e ) reached to 37.0 mg⋅g −1 at the equilibrium Li + concentration was 85.2 mg⋅L −1 , which is significant for lithium extraction from aqueous solutions with very low lithium content. Besides, the sorption isotherm presents a kind of L‐type isotherm according to the classification, which demonstrates that there was no strong competitive force between the solvent and sorbate to occupy the adsorption sites . In order to obtain the maximum adsorption capacity and the optimum conditions for Li + recovery, two most widely used equilibrium models were employed to carry out the equilibrium lithium adsorption data ( q e VS. c e ).…”

“…In order to interpret the experimental data, the time‐dependent sorption data were analyzed using the linear form of the pseudo‐first‐order and pseudo‐second‐order kinetics equation . Because the models were more likely to predict the behavior over the entire sorption period and was in agreement with the fact that the chemical sorption was the rate‐controlling step . The pseudo‐first‐order (equation 3) and pseudo‐second‐order sorption model (equation 4) are given as following:…”

Li4Mn5O12 with nanotubes morphology was successfully prepared by hydrothermal and solid phase reaction. The as‐obtained adsorbent was determined by X‐ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscope (TEM) and N2 ad/desorption technologies. The characterization results indicated that spinel H4Mn5O12 took on two‐dimensional nanotubes morphology with the diameter of pore ∼200 nm, BET surface area is 92.997 m2⋅g−1, and the corresponding pore size centers at 3.4, 35.9 and 156.5 nm. The adsorption experimental results showed that the maximum Li+ adsorption capacity of H4Mn5O12 was as high as 37.0 mg⋅g−1, and the adsorption process fit well with Langmuir model. In addition, adsorption kinetic experimental data were well fitted by the pseudo‐second‐order model, which indicated the adsorption process followed chemisorption involving in ion exchange. The effects of co‐existing cations on lithium recovery suggested that Na+, K+, Ca2+ and Mg2+ ions had very small effect on recovery of lithium. The regeneration of H4Mn5O12 for the multicyclic Li+ adsorption and desorption were also assessed. The result implied that most of Li+ could be desorbed within 40 min, but the adsorption capacity decreased when the number of cycles was five, which indicated that the structure of H4Mn5O12 was needed to be improved. Lithium adsorption onto H4Mn5O12 could be attributed to electrostatic interaction and ion exchange between Li+ and H+ according to the results of adsorption isotherm and kinetics properties.

Recent Advances in the Lithium Recovery from Water Resources: From Passive to Electrochemical Methods

et al. 2022

The ever-increasing amount of batteries used in today's society has led to an increase in the demand of lithium in the last few decades. While mining resources of this element have been steadily exploited and are rapidly depleting, water resources constitute an interesting reservoir just out of reach of current technologies. Several techniques are being explored and novel materials engineered. While evaporation is very time-consuming and has large footprints, ion sieves and supramolecular systems can be suitably tailored and even integrated into membrane and electrochemical techniques. This review gives a comprehensive overview of the available solutions to recover lithium from water resources both by passive and electrically enhanced techniques. Accordingly, this work aims to provide in a single document a rational comparison of outstanding strategies to remove lithium from aqueous sources. To this end, practical figures of merit of both main groups of techniques are provided. An absence of a common experimental protocol and the resulting variability of data and experimental methods are identified. The need for a shared methodology and a common agreement to report performance metrics are underlined.
