Sulfonation of chitosan for enhanced sorption of Li(I) from acidic solutions – Application to metal recovery from waste Li-ion mobile battery

“…acid (at 1% concentration, w/w). Indeed, the addition of oxalic acid was frequently reported for improving the separation of Li(I) from other cations [16,38,39]. This is explained by the preferential complexation of heavy metals by oxalate (compared with lithium).…”

Metals Recovery from Seawater Desalination Brines: Technologies, Opportunities, and Challenges

“…Finally, a techno-economic analysis is necessary to implement these technologies in practical cases. For instance, selective Li recovery from seawater mining with a conventional chemical precipitation approach involves multiple steps that may be chemically intensive and time consuming . Meanwhile membrane electrochemical-driven systems such as electrodialysis (ED) and membrane capacitive deionization (MCDI) are promising as rapid and low-chemical recovery processes for Li recovery. , To date, no detailed techno-economic assessment of electrochemical processes has been carried out.…”

Lithium-Sodium Separation by a Lithium Composite Membrane Used in Electrodialysis Process: Concept Validation

“…For lithium recovery from its aqueous resources, generally as LiCl or LiCO 3 salt [9], several methods were proposed, including solar evaporation [10], adsorption [11][12][13][14][15], complexation [16][17][18][19], precipitation [20,21], solvent extraction [22,23] and membrane process [24][25][26][27][28]. Among these proposed techniques and despite the time consumption and environmental effects of solar evaporation, this remains the most used method for actual lithium salt production [29].…”
