Preparation and adsorption performance of multi-morphology H1.6Mn1.6O4 for lithium extraction

Study of Forward Osmosis Process and its Effects on the Concentration of Salt Lake Brine

“…= Re Lu (23) where Re is the Reynolds number, μ is the dynamic viscosity, ρ is the density of DS, and L is the channel length of the FO test cell.…”

“…Therefore, it is essential to develop a low-energy, low-cost, and pollution-free approach for brine enrichment. Recently, several major methods have been used to extract lithium from brine in salt lakes, including solvent extraction, − specific identification of adsorption and desorption, − and membrane techniques. ,,, However, solvent extraction requires energy to sustain mechanical vibrations to achieve phase-to-phase contact, , and the acid used in the desorption process is likely to increase costs and pollute the environment . Similarly, although membrane technologies have been applied in the treatment of saline wastewater , and studies have shown that reverse osmosis (RO) and nanofiltration (NF) possess certain concentration effects, ,, pressure- or electricity-driven methods of separation or concentration inevitably require large amounts of energy.…”

An ion-sieve-tailored biomimetic porous nanofiber as an efficient adsorbent for extraction of lithium from brine

“…The spinel-type H 1.6 Mn 1.6 O 4 as a lithium-ion sieve adsorbent shows high selectivity for Li + , with this selectivity attributed to steric hindrance. [28][29][30][31][32] Therefore, it is urgent to develop high-performance lithium-adsorption materials based on H 1.6 Mn 1.6 O 4 . The natural towel gourd with a uniform threedimensional fiber skeleton structure inspires our design of materials.…”
