Application and Mechanism of Lithium-ion Sieves in the Recovery of Lithium-Containing Wastewater: a Review
Water, Air, & Soil Pollution(2024)
摘要
As a crucial component of modern energy, lithium is becoming ever more vital. As a result, lithium-ion-containing wastewater is being created in huge quantities, causing resource loss and environmental damage that must be effectively treated. Adsorption techniques are popular for lithium extraction and recovery due to their benefits of low energy usage, straightforward procedures and excellent recycling. The lithium-ion sieves (LISs) adsorption technique, which has the qualities of high lithium selectivity and adsorption capacity, low energy consumption, environmental protection and safety, is now regarded as the most promising lithium extraction technology. LISs composite forming technology (such as granulation, foaming, fiber forming, film forming and magnetization) and the adsorption technique, specifically the LISs adsorption mechanism, are discussed in this review. The effectiveness of extracting lithium from lithium-containing solutions using LISs adsorbents is reviewed and the difficulties of recovering lithium resources by LISs are presented, thereby offering a guide for their use in treating wastewater containing lithium.
