This paper presents a comprehensive review of studies on electrodialysis (ED) applications in wastewater treatment, outlining the current status and the future prospect. ED is a membrane process of separation under the action of an electric field, where ions are selectively transported across ion-exchange membranes. ED of both conventional or unconventional fashion has been tested to treat several waste or spent aqueous solutions, including effluents from various industrial processes, municipal wastewater or salt water treatment plants, and animal farms. Properties such as selectivity, high separation efficiency, and chemical-free treatment make ED methods adequate for desalination and other treatments with significant environmental benefits. ED technologies can be used in operations of concentration, dilution, desalination, regeneration, and valorisation to reclaim wastewater and recover water and/or other products, e.g., heavy metal ions, salts, acids/bases, nutrients, and organics, or electrical energy. Intense research activity has been directed towards developing enhanced or novel systems, showing that zero or minimal liquid discharge approaches can be techno-economically affordable and competitive. Despite few real plants having been installed, recent developments are opening new routes for the large-scale use of ED techniques in a plethora of treatment processes for wastewater.

Electro-Driven Materials and Processes for Lithium Recovery—A Review

The mass production of lithium-ion batteries and lithium-rich e-products that are required for electric vehicles, energy storage devices, and cloud-connected electronics is driving an unprecedented demand for lithium resources. Current lithium production technologies, in which extraction and purification are typically achieved by hydrometallurgical routes, possess strong environmental impact but are also energy-intensive and require extensive operational capabilities. The emergence of selective membrane materials and associated electro-processes offers an avenue to reduce these energy and cost penalties and create more sustainable lithium production approaches. In this review, lithium recovery technologies are discussed considering the origin of the lithium, which can be primary sources such as minerals and brines or e-waste sources generated from recycling of batteries and other e-products. The relevance of electro-membrane processes for selective lithium recovery is discussed as well as the potential and shortfalls of current electro-membrane methods.

Facilitating the accurate recognition of lithium ions (Li + ) by filtration membranes is of great significance for the efficient and selective separation of Li + from saline lake brine and seawater. Herein, a highly porous self-supporting graphene oxidebased (GCS) membrane modified by single-walled carbon nanotubes (SWCNTs) and 4-aminobenzo-12-crown-4 (AB12C4) was fabricated via a facile and versatile vacuum filtration method. The highly porous structure constructed with polystyrene microspheres as a self-sacrificial template could provide a larger contact area at the solid−liquid interface. Moreover, the addition of electric SWCNTs endows the GCS membrane with a tunable adsorption behavior by an external electric field. Meanwhile, the decoration of AB12C4 on the multilayered GCS membrane realizes a specific recognition of Li + with an excellent adsorption capacity of 37.0 mg g −1 , exhibiting considerably high separation factors against Na + (18.97), K + (26.19), Mg 2+ (16.67), and Ca 2+ (19.64). According to the density functional theory calculations, the adsorption of GCS membrane for Li + is more thermodynamically favorable than that of the contrast ions. This work demonstrates an effective approach with the convenient vacuum filtration technology for the selective adsorption of Li + , which could alleviate the shortage of lithium resources.
