“…They found that HMnO(Mg) was selective for lithium over both monovalent and divalent cations, with a selectivity sequence of Mg < Ca < Sr < Ba < Na = K << Li at pH 8. The MnOx sorbents of composition HMnO(Ca), HMnO(Sr), and HMnO(Ba) had lower selectivity and Recepoglu et al [142] investigated the adsorption of lithium from geothermal water using both powdered and granulated forms of lambda-MnO 2 derived from spinel-type lithium manganese dioxide. The sorbents were tested using batch-equilibrium experiments, adsorption kinetics were measured, and intra-particle diffusion was found as the ratecontrolling step [142].…”

Lithium is the principal component of high-energy-density batteries and is a critical material necessary for the economy and security of the United States. Brines from geothermal power production have been identified as a potential domestic source of lithium; however, lithium-rich geothermal brines are characterized by complex chemistry, high salinity, and high temperatures, which pose unique challenges for economic lithium extraction. The purpose of this paper is to examine and analyze direct lithium extraction technology in the context of developing sustainable lithium production from geothermal brines. In this paper, we are focused on the challenges of applying direct lithium extraction technology to geothermal brines; however, applications to other brines (such as coproduced brines from oil wells) are considered. The most technologically advanced approach for direct lithium extraction from geothermal brines is adsorption of lithium using inorganic sorbents. Other separation processes include extraction using solvents, sorption on organic resin and polymer materials, chemical precipitation, and membrane-dependent processes. The Salton Sea geothermal field in California has been identified as the most significant lithium brine resource in the US and past and present efforts to extract lithium and other minerals from Salton Sea brines were evaluated. Extraction of lithium with inorganic molecular sieve ion-exchange sorbents appears to offer the most immediate pathway for the development of economic lithium extraction and recovery from Salton Sea brines. Other promising technologies are still in early development, but may one day offer a second generation of methods for direct, selective lithium extraction. Initial studies have demonstrated that lithium extraction and recovery from geothermal brines are technically feasible, but challenges still remain in developing an economically and environmentally sustainable process at scale.

Bu çalışmanın amacı kullanımı giderek artan ve değerli bir metal olan lityumun (Li) sulu çözelti içerisinde pomza adsorbanları ile geri kazanımının araştırılmasıdır. Bu amaç kapsamında manyetik demir kaplı pomza, MnO2 kaplı pomza ve Mn kaplı pomza malzemeleri hazırlanarak adsorpsiyon yöntemiyle Li giderimi karşılaştırılmıştır. Çalışmada ayrıca farklı sıcaklıkların, adsorpsiyon süresinin ve çözelti pH değerlerinin Li adsorpsiyonu üzerine etkisi de belirlenmiştir. MnO2 kaplı pomzanın SEM-EDX ve FTIR analizleri yapılarak özellikleri belirlenmiştir. Yapılan çalışma sonucunda demir kaplı pomza ile Li giderimi sağlanamasa da mangan kaplı pomzalar ile Li adsorpsiyonu gerçekleşmiştir. En yüksek giderimin sağlandığı MnO2 kaplı pomza ile yapılan çalışmalarda 1 saat adsorpsiyon süresinden sonra giderim veriminin değişmediği, sıcaklığın Li giderimine bir etkisinin olmadığı görülmüştür. Fakat çözelti pH değeri lityum gideriminde önemli olup, en yüksek Li giderimi (% 40) pH 9 değerinde elde edilmiştir. Bu giderim değeri düşük olmakla birlikte özellikle deniz suyundan tatlı su eldesi veya jeotermal sulardan Li kazanımı prosesleri için uygun ön arıtma alternatifi oluşturacaktır.

“…Several adsorbents such as lithium manganese oxides (LMOS), ion sieves, H 2 TiO 3 [10], and ion-imprinted polymers [11] have been prepared for the adsorption of lithium. Among them, the most common inorganic adsorbents are the LMOS [12][13][14] and ion sieves, which have good adsorption capacities and selectivities [15]. However, these adsorbents with powder forms cannot be practically used due to the loss of adsorbents in their applications [16,17].…”

Efficient Adsorption Performance of Lithium Ion onto Cellulose Microspheres with Sulfonic Acid Groups

The separation of Li+ from an aqueous solution has received much attention in recent years because of its wide application in batteries and nuclear energy. A cellulose microsphere adsorbent with sulfonic acid groups (named as CGS) was successfully prepared by the pre-irradiation-induced emulsion graft polymerization of glycidyl methacrylate onto cellulose microspheres through subsequent sulfonation and protonation. The adsorption performance of Li+ onto the CGS adsorbent is investigated in detail. The as-prepared CGS adsorbent exhibited fast adsorption kinetics and a high adsorption capacity of Li+ (16.0 mg/g) in a wide pH range from 4 to 10. The existence of K+ and Na+ was found to have the ability to affect the adsorption capacity of Li+ due to the cation-exchange adsorption mechanism, which was further confirmed by X-ray photoelectron spectroscopy (XPS). The column adsorption experiment indicated that the adsorption capacity of CGS agreed well with the batch adsorption, and a fast desorption could be obtained in 10 min. It is expected that CGS has potential usage in the adsorption separation of Li+ from an aqueous solution.
