“…Therefore, it is necessary to achieve stable and sustainable lithium recovery from nature. Lithium resources exist in lithium ores, seawater, and salt lake brine [9][10][11]. Lithium in salt lake brine accounts for approximately 80% of the total lithium resources [2], making it one of the most important lithium sources.…”

Lithium recovery is imperative to accommodate the increase in lithium demand. Salt lake brine contains a large amount of lithium and is one of the most important sources of lithium metal. In this study, Li2CO3, MnO2, and TiO2 particles were mixed, and the precursor of a manganese–titanium mixed ion sieve (M-T-LIS) was prepared by a high-temperature solid-phase method. M-T-LISs were obtained by DL-malic acid pickling. The adsorption experiment results noted single-layer chemical adsorption and maximum lithium adsorption of 32.32 mg/g. From the Brunauer–Emmett–Teller and scanning electron microscopy results, the M-T-LIS provided adsorption sites after DL-malic acid pickling. In addition, X-ray photoelectron spectroscopy and Fourier transform infrared results showed the ion exchange mechanism of the M-T-LIS adsorption. From the results of the Li+ desorption experiment and recoverability experiment, DL-malic acid was used to desorb Li+ from the M-T-LIS with a desorption rate of more than 90%. During the fifth cycle, the Li+ adsorption capacity of the M-T-LIS was more than 20 mg/g (25.90 mg/g), and the recovery efficiency was higher than 80% (81.42%). According to the selectivity experiment, the M-T-LIS had good selectivity for Li+ (adsorption capacity of 25.85 mg/g in the artificial salt lake brine), which indicates its good application potential.

In this work, Magnesium oxide (MgO) adsorbents were synthesized by coprecipitation method via natural bischofite (MgCl2 ⋅ 6H2O, ≥96 wt %) as magnesium source, two different morphologies of MgO nanomaterials, flower‐spheres‐like (MgO−S1) and lamellas‐like (MgO−L1), were successfully synthesized by control of synthesis conditions. The adsorption experimental results showed on Congo Red (CR) dye that both MgO−S1 and MgO−L1 exhibit outstanding adsorption performance with a high adsorption quantity (about 2000 mg ⋅ g−1). Langmuir was the most suitable model to describe the adsorption isotherm. The adsorption kinetics of CR are in accord with the pseudo‐second‐order kinetics (PSO). As a control, flower‐spheres‐like (MgO−S2) and lamellas‐like (MgO−L2) were synthesized by commercial MgCl2 ⋅ 6H2O, and their adsorbing performance on CR dye in wastewater was studied. The results show that MgOs prepared by different Mg resources took on exactly the same shape and nearly the same adsorption properties.

“…Statistically, 8–10 tons of magnesium chloride would be generated for every 1 ton of potassium chloride production . Consequently, hundreds of millions of tons of waste magnesium chloride were not utilized and accumulated in the Qinghai saline lake, and a large number of magnesium chloride byproducts were redischarged into the saline lake or stored in the form of solid waste, which not only caused a serious waste of magnesium resources and damage to the saline lake ecological environment but also affected the sustainable production of potash fertilizer. , On the other hand, the situation, unfortunately, has become worse in recent years since the lithium extraction from the saline lake has accelerated due to the huge demand for lithium in the lithium battery industry, which is also accompanied by the accumulation of magnesium resources. ,, Therefore, the comprehensive utilization of magnesium resources in saline lakes has become an important strategic problem to be solved.

Two organic layered double hydroxides (OLDHs) intercalated by UV absorbents of para-aminobenzoic acid (PABA) and cinnamic acid (CA) were synthesized by the anion-exchange method, and their structures and properties were characterized. Then, the two OLDHs were applied to modify asphalt together with two different antioxidants, octadecyl-3-(3,5-di-tert-butyl-4hydroxyphenyl)-propionate (1076) and pentaerythritol tetrakis (3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate) ( 1010), aiming at synergistically enhancing the aging resistance of asphalt. The aging behaviors of modified asphalt were evaluated by the analyses of physical properties and chemical structures of modified asphalt after pressurized aging vessel (PAV) and ultraviolet (UV) aging tests. The results indicated that PABA and CA were successfully intercalated into the interlayers of LDHs and that the lipophilicity and UV absorbance of LDHs were significantly improved due to the organic intercalation. Hence, OLDH-modified asphalt presented enhanced anti-UV aging performance compared with LDH-modified asphalt. Meanwhile, the addition of organic LDH/ antioxidant composites could further improve the antiaging performance of asphalt, including thermal-oxidation and photo-oxidation aging resistance, exhibiting a synergistic effect. Furthermore, different combinations of OLDHs and antioxidants had different improvement effects on the aging properties of asphalt; to be specific, the composites of 1076/PABA-LDHs and 1010/CA-LDHs were superior to those of 1010/PABA-LDHs and 1076/CA-LDHs, respectively, in promoting the aging resistance of asphalt.
