Separation and utilization of lithium, magnesium, and boron resources from salt lakes through Ionic liquid extraction and CO2 mineralization

Salt lake is abundant in three crucial resources − lithium(Li), magnesium(Mg), and boron(B). The separation efficiency of these resources is low, the excessive use of acid and the environmental harm caused by the accumulation of magnesium source after Li+ extraction still exist. In this work, a new process of step-by-step extraction of B-Li and Mg mineralisation is proposed to separate the three resources. Boron was extracted using 2-ethyl-1,3-hexanediol (EHD) + kerosene, and it was found that the addition of FeCl3 could significantly improve the boron extraction rate(E). In the R(O:A) = 1:3, 40 %EHD + 60 %kerosene, adding 0.15 mol/L FeCl3, after three-stage countercurrent extraction, the E(B3+) reached 99 %, E(Fe3+), E(Li+) and E(Mg2+) less than 4 %. Tributyl Phosphate (TBP)-Ionic Liquids (ILs)-kerosene-FeCl3 system was used to extract Li+, the ILs and FeCl3 existed in the extraction process with a competitive behaviour. The extraction efficiency of lithium was improved by cationic [C4mim+] exchange reaction. Under the conditions of R(O:A) = 1:1, 5 %ILs + 65 %TBP + 30 %kerosene, three-stage extraction, the E(Li+) was reached 91 %. (NH4)2CO3 was used to mineralise the magnesium resources. Reaction temperature of 40 °C, the product was magnesium carbonate trihydrate(MgCO3·3H2O) with a smooth surface and rod-like structure, and the conversion rate reached 85 %. At 75 °C, the product was irregular spheroidal basic magnesium carbonate(4MgCO3·Mg(OH)2·5H2O) with a magnesium conversion of 91.7 %.

Study on 13C MultiCP/MAS ssNMR Analysis of Tobacco Pectin

Background: As one of the most important economic crops, tobacco products have a long history and dominate the development of the world economy. Pectin, as a complex colloidal substance widely present in plant cell walls, its content is an important factor affecting the safety of tobacco smoking. Objective: This study aimed to analyze the content and structure of pectin in tobacco samples Methods: In this study, tobacco pectin was extracted by ultrasonic-assisted ionic liquid extraction, and the 13C MultiCP/MAS NMR spectral analysis of pectin was conducted. Results: The type of extractant, duration of ultrasonication, extraction temperature, and solid-liquid ratio were optimized. Under the conditions of using 1-Butyl-3-methylimidazolium tetrafluoroborate ([Bmim]BF4) as the extractant, the solid-liquid ratio of 1:20 g/mL, and the ultrasonic power of 600 w for 30 min at 30°C, the yield of 23.7% of tobacco stem pectin and the purity of 54.2% could be obtained. The optimized MultiCP sequence parameters, with 10 CP cycles of 1.0 ms and the repolarization time of 50 ms could obtain high-resolution spectra within a time of 1.0 h. The C-6 peaks of the pectin in spectra were fitted using the spectral deconvolution technique and calculated the methylesterification (DM) of the tobacco pectin, which was generally less than 50% and belonged to the low methyl esterification pectin. The pectin content of the tobacco sample was calculated using the standard curve method with the addition of dimethyl sulfone (DMS) as an internal reference. The results of this method were consistent with the colorimetric method. Conclusion: The 13C MultiCP/MAS NMR method has the advantages of being green, fast, and accurate and provides a new technical tool for quantitative and qualitative studies of cell wall substances in tobacco samples.

Mechanism of selectivity of tri-n-octylmethylammonium chloride for vanadium

Ionic liquid (IL)-based extraction is a promising and environmentally benign separation technology. Processes for quaternary ammonium-based IL extraction of vanadium have been extensively studied, but the vanadium extraction mechanism has not been accurately confirmed. This study investigated vanadium extraction from sulphuric acid leachate of shale by solvent extraction with tri-n-octylmethylammonium chloride (TOMAC/CH3NClR3). The results indicated that 90.50 % of the vanadium extraction percentage comprised one stage under the optimal condition experiments. These experiments were carried out at pH 1.8; the IL phase consisted of 25 vol% TOMAC, 15 vol% TBP, and 60 vol% sulfonated kerosene; O/A phase ratio of 1:7.5; extraction time of 120 s. The forms of vanadium and impurities present were revealed by the solution chemistry, Medusa software simulation. The extraction mechanism of vanadium was investigated using ultraviolet spec-trophotometer (UV–Vis), fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance spectroscopy (NMR), and hotometer matrix-assisted laser-resolved ionization time-of-flight mass spectra (MALDI-TOF-MS). Under extraction conditions at pH 1.8, vanadium was present as an anion in the form H2V10O4- 28 and HV10O5- 28. Since the extraction mechanism of TOMAC was anion exchange, the extracted vanadium was mainly present as the anionic complex [(CH3NR3)4·H2V10O4- 28]/[(CH3NR3)5·HV10O5- 28]. The ESP map of TOMAC and V (V) was calculated to confirm the reaction sites and was used to verify the anion exchange mechanism.

This review provides an overview of the occurrence of REEs in e-waste and discusses both conventional and emerging green technologies for their recovery. Conventional methods include physical separation, hydrometallurgy, and pyrometallurgy, while innovative approaches such as bioleaching, supercritical fluid extraction, ionic liquid extraction, and lanmodulin-derived peptides offer improved environmental sustainability and efficiency. The article presents case studies on the extraction of REEs from waste permanent magnets and fluorescent powders, highlighting the specific processes involved. Future research should focus on developing eco-friendly leaching agents, separation materials, and process optimization to enhance the overall sustainability and efficiency of REE recovery from e-waste, addressing both resource recovery and environmental concerns effectively.

Direct lithium extraction from Canadian oil and gas produced water using functional ionic liquids – A preliminary study

In this study, a functional ionic liquid system was successfully applied to extract lithium from the Canadian oil and gas produced water samples without further dilution at ambient conditions. The effects of interference cations, dissolved organics and other factors on the extraction were studied in detail. Chemical precipitation method was applied to reduce the concentrations of divalent ions before the ionic liquid extraction. The extraction efficiency is about 70% on average and can be as high as 90%. It appears that this extraction method can be directly applied to the oilfield brine samples with both high Na/Li and Mg/Li ratios. In addition, it seems that the dissolved organics in the produced water did not impact the extraction efficiency. Efforts shall be made in the future to reduce the cost by replacing the diluent with another type of solvent and further improving the recycle and reuse of the IL systems. In summary, the technology can achieve satisfactory lithium extraction from the Canadian oil and gas produced water.

Influence of ionic liquid (R4PSCN) for selective separation and recovery of copper from spent Cu[sbnd]Cr catalyst leach liquor

Separation and recovery of copper (Cu) from sulphate mediated CuCr spent catalyst leach solution through solvent extraction approach has been systematically investigated. A number of Ionic Liquid (IL) and other conventional extractants were used while investigating the selectivity and efficient extraction tendency of either IL or extractants towards Cu(II). In context of copper extraction efficiency, the adopted organic reagents followed the descending order: R4PSCN > R4PD > R4PCy > Cyphos 101 > Aliquot 336 > D2EHPA > Cyanex 272. The extraction behavior of Cu(II) was established based on slope analysis method. From the results it was noticed that extraction occurs through a cation exchange mechanism with association of a mole of Cu(II) per mole of R4PSCN. The plot of log D vs. log [R4PSCN] yield a linear relationship with a slope close to 4 which is used to propose extraction reaction mechanism/ stoichiometry. The nature of complex between Cu(II) and IL was further examined using FTIR analysis of the loaded organic phase with the diluent. Mc-Cabe Thiele diagram was constructed to predict quantitative extraction of Cu(II) which revealed the need for two stages at aqueous to organic (A:O) phase volume ratio of =3:1. The stripping isotherm constructed at optimum NH4OH concentration (0.4 M) suggests the need for two stages at O:A phase volume ratio of = 2:1 for complete stripping of copper with regeneration of R4SCN for further use. Both isotherm conditions were validated by 6 cycles of counter current simulation (CCS) study for obtaining the desired amount of Cu(II) loaded R4SCN (during extraction) and/or stripped copper solution (during stripping). Overall copper enrichment was ∼6 fold leading to produce a copper(II) solution of 48 g/L from 6 g/L Cu(II). The stripped solution was subjected to crystallization study to produce copper sulphate crystals of high purity and was confirmed by XRD analysis of crystal phases.

An updated review of composition, health benefits, and applications of phenolic compounds in Ficus Carica L.

AbstractFicus carica L. (FC) is rich in phenolic compounds such as phenolic acids, flavonoids, and anthocyanins. Phenolic compounds in FC show remarkable health benefits and applications. The composition of phenolic compounds in FC can vary with some factors, such as variety, ripeness, geographical location, extraction methods and processing methods. New techniques such as supercritical fluid extraction, subcritical water extraction and ionic liquid extraction should be further developed and combined with traditional techniques to obtain higher quality sources of phenolic compounds. Numerous in vivo and in vitro studies reported healthy benefits of phenolic compounds in FC, such as anti‐oxidant, anti‐inflammatory, anti‐diabetic, anti‐obesity, anti‐cancer and anti‐Alzheimer's. Further works are required to reveal mechanisms and structure‐activity relationships, such as targeted metabolomics and pharmacological studies. In terms of applications, phenolic compounds in FC as prebiotics on the intestinal flora need to be further studied to expand their applicability in food fermentation. In a word, this review highlights the remarkable health benefits and application value of phenolic compounds in FC.

Resources recovery-rubidium recovery from desalination brine through hydrometallurgy techniques

Because of the water scarcity in many regions, different methods have been implemented to address this problem. The desalination technique is known as a practical solution among them. However, brine from the desalination process, which contains high concentrations of salts, minerals, and chemicals, will cause environmental harm to the sea, soil, and groundwater if it is not properly treated. Therefore, recovering critical resources from brine is essential for reducing brine disposal. This study aims to apply two hydrometallurgy systems, namely ion exchange and ionic liquid extraction, to circulate rubidium resources from brine. Dowex G26 resin was employed in the ion exchange system, and the adsorption isotherm model and saturated adsorption capacity were explored initially. The optimal parameters such as pH value, L/S ratio (liquid/solid), adsorption period, and adsorption temperature will then be investigated. In the ionic liquid extraction process, the t-BAMBP/C2mimNTf2 system (4-tert-Butyl-2-(α-methylbenzyl) phenol/1-ethyl-3-methylimidazolium bis(trifluoromethyls​ulfonyl)​imide) was used, and the parameters including pH value, concentrations of t-BAMBP, (O + I)/A ratio (organic + ionic liquid/aqueous), extraction time, and extraction temperature will be optimized as well. The results reveal that adsorption capacity and extraction efficiencies were 14.3 mg g− 1 and 86%, respectively. Furthermore, suitable reagents, including HCl and HNO3, were applied to desorb and strip rubidium from the Dowex G26 and t-BAMBP/C2mimNTf2 systems. To sum up, environmental hazards of desalination brine and rubidium resources can be reduced and recovered through the two different extraction systems.

Application of ionic liquid extractant in enhanced separation of 2-propanol-n-hexane azeotrope system

2-Propanol and n-hexane are widely used (as) chemical reagents in electronic, pharmaceutical, and chemical industries. An efficient separation of the azeotropic system of 2-propanol-n-hexane is of profound practical significance. By using the conductor-like screening model for real solve (COSMO-RS) predictive model, ionic liquids as extractants for separating the azeotropic system of 2-propanol-n-hexane were evaluated with selectivity coefficients (S) and capacity (C) as the evaluation indexes. Based on the evaluation results, one high-performance extractants named hydroxylamine Cl (C8A19) was selected from 435 kinds of ionic liquids designed by combining 29 kinds of anions and 15 kinds of cations. Moreover, the reliability of the model in predicting the vapor–liquid phase equilibrium behavior of 2-propanol-n-hexane system was verified. Then, the effect of C8A19 on the vapor–liquid phase equilibrium of the 2-propanol-n-hexane system was investigated theoretically and experimentally. The results show that the azeotrope of the system can be broken when the molar fraction of C8A19 is 0.02, denoting that C8A19 can be used for enhanced separation of 2-propanol-n-hexane system. On the basis of the aforementioned study, the selectivity mechanism of the extractant was analyzed from the perspective of microscopic molecular interactions by using the descriptor (σ-profiles) of COSMO-RS. This study provides both theoretical and data support for further designing high-performance ionic liquid extractants and extraction process.

Ionic liquid microwave-assisted hydrodistillation extraction of Angelica sinensis essential oil and its own anti-inflammatory and antioxidant activities

In this study, ionic liquid microwave-assisted hydrodistillation (IL-MAHD) was employed to overcome the challenges of substantial emulsification and low extraction yield which occur in the extraction process of Angelica sinensis essential oil (AEO). Additionally, an online detection system was introduced into the AEO extractor to enable real-time monitoring during the extraction process. Optimal conditions were determined as follows: material-to-liquid of 1:10, ionic liquid concentration of 0.5%, microwave power of 400 W, extraction time of 4 h, condensation temperature of 20 °C, and cooling temperature of 40 °C. Under these optimized conditions, the AEO yield reached 0.7707%, marking a 1.4066-fold increase compared to microwave-assisted hydrodistillation (MAHD) and a 3.7615-fold increase compared to hydrodistillation (HD). Meanwhile, IL-MAHD exhibited the highest relative content of (Z)-ligustilide (73.424%), and the corresponding AEO displayed significant anti-inflammatory and antioxidant effects at concentrations of 7.8125, 15.625, and 31.25 µg/g. The results of extraction kinetics and online monitoring suggested that the IL-MAHD achieved the fastest extraction yield of AEO. This study provides a new perspective on exploring a potential cost-efficient technology for the industrial extraction of essential oils.

Ionic liquid assisted extraction induced by emulsion breaking for extraction of trace metals in diesel, gasoline and kerosene prior to ICP-OES analysis

This study describes a novel and greener ionic liquid assisted extraction induced by emulsion breaking (ILA-EIEB) method for extraction of As, Ba, Cd, Cr, Ni Pb, Sb, Sn, Tb, Te and V in fuel oils. The most influential extraction parameters were ionic liquid concentration [(1-Ethyl-3-methylimidazolium bis (trifluoromethylsulfonyl)], HNO3 concentration, Triton X-100 concentration, and sample mass and were optimised by using full factorial and Box-Behnken designs. The optimum conditions obtained were 0.035 % 1-Ethyl-3-methylimidazolium bis (trifluoromethylsulfonyl) concentration, 18 % v/v HNO3 concentration, 15 % w/v Triton X-100 concentration, and 0.1 g sample mass. The emulsions were fully broken by using a controlled heating water bath at temperature of 80 ± 2 °C for 30 ± 4 min, followed by centrifugation at 3500 rpm for 15 min. Under the optimum conditions, the proposed ILA-EIEB method was accurate (80.1–101 %) and precise (1.9–4.7 %) for all the investigated metals. The method detection limits were 0.107, 0.013, 3.494 and 0.560 μg/g for Ba, Na, Ni and V, respectively. The optimised ILA-EIEB method was then applied in real fuel samples and metal concentration levels ranged from 0.072 to 8.610 μg/g, which were consistent with other literature reported work. Therefore, this study suggests that the examined metal ions present in fuel oils commercialised in Johannesburg, South Africa are in tolerable concentration levels and are not a threat.

Customizable cholinium-based aqueous biphasic systems as ecofriendly extraction platform for removal of pesticide from wastewaters

This study explores the use of a series of cholinium ionic liquids (ILs) or salts in combination with polypropylene glycol 400 to form aqueous biphasic systems (ABS) for extracting various polarity pesticides (dicamba, clomazone, pyraclostrobin, and deltamethrin) from water. We assessed five cholinium-based salting-out agents ([Ch][DHP], [Ch]Cl, [Ch][Ac], [Ch][Lac], and [Ch][Nic]), chosen for their structural diversity and unique properties, such as high salting-out potential and different ability to undergo specific interactions. Liquid-liquid equilibrium phase diagrams were established, and partition experiments were conducted to evaluate extraction efficiency. Different partition patterns were obtained for studied pesticides, with [Ch][DHP] demonstrating the highest efficiency exceeding 90 % for each target pesticide due to its strong salting-out ability. On the other hand, more diverse partition trends due to specific interactions were obtained for low-melting cholinium-ILs ABS. The effect of pH and temperature on the partitioning behavior in [Ch][Ac]-based ABS highlighted the cholinium ILs extraction system's customizable nature. Focusing on [Ch]Cl for its eco-friendly aspects, widespread availability and excellent extraction performance, we optimized parameters for the removal of pesticides from real samples, applying the technology to spiked agricultural wastewater with an extraction efficiency of over 99 %. Our findings demonstrate the potential of cholinium-based IL-ABS in reducing environmental pollution through efficient pesticide extraction.

Optimizing the method for removing MSNs templates using an ionic liquid ([C4mim]Cl)

The key step in preparing mesoporous silica is to remove the organic template agent, and the most common method used to achieve this goal is high-temperature calcination. However, this method has many disadvantages, one of which is that it reduces the silanol density on the surface of mesoporous silica, which affects its subsequent modification. Ionic liquids (ILs) are often used as extractants. In this work, the 1-butyl-3-methylimidazolium chloride ([C4mim]Cl) IL is considered, and the effects of its concentration, reaction temperature, and reaction time as well as HCl concentration on the extraction rate and silanol density were investigated using an IL extraction template agent (cetyl trimethyl ammonium bromide (CTAB)). The results show that an IL concentration of 10%, a reaction temperature of 120 °C, a reaction time of 12 h, and an HCl concentration of 1% are the best reaction parameters; with these parameters, the extraction rate and the silanol density were found to be 93.19% and 2.23%, respectively. The silanol density of mesoporous silica treated by calcination is only 0.81%. A higher silanol density provides more reaction sites, so that the modified mesoporous silica treated with the IL can be loaded with more Zn ions.

Sono-Microwave Assisted Chlorine free and Ionic Liquid (SMACIL) extraction of cellulose from Urtica dioica: A benign to green approach

The extraction of cellulose using eco-friendly solvents has been gaining significant attention for a couple of decades. This study investigated the impact of benign and green solvents on the extraction, thermal stability, mechanical properties, and crystallinity of cellulose extracted from Urtica dioica (Stinging nettle) using a Sono-Microwave Assisted Chlorine free and Ionic Liquid (SMACIL) extraction technique. In this regard, the stalks were undergone through pre chemical treatment before starting bleaching them with hydrogen peroxide (HPO) and 1-butyl-3-methylimidazolium acetate (BMIM-Ac) having different mole ratios (5, 7.5, and 10) to expose cellulose. The Urtica dioica cellulose (UDC) was characterized using FTIR, tensile testing, FESEM, XRD, and TGA. The fibrillation and lumen can be seen in SEM images that confirm the extraction of cellulose. The results showed that the BMIM-Ac-10 gives the maximum cellulose yield (88 %) than other compositions. Moreover, the cellulose extracted using BMIM-Ac-10 has high mechanical strength which makes it a potential constituent for various applications in the field of materials science. These results have significant implications for the development of sustainable and efficient processes for the extraction of cellulose.

Extraction of Pyrrole from Its Mixture with n-Hexadecane Using Ionic Liquids and Their Binary Mixtures.

The conventional hydrodenitrogenation method is expensive and involves the use of catalysts and harsh procedures. In the last few years, ionic liquids (ILs) have gained attention as a promising alternative solvent for fuel oil extractive denitrogenation. In this work, the Conductor-like Screening Model for Real Solvents (COSMO-RS) was used to screen 173 potential ILs as solvents for fuel oil. Two ILs (1-ethyl-3-methylimidazolium dicyanamide ([EMIM][N(CN)2]) and 1-ethyl-3-methylimidazolium methanesulfonate ([EMIM][MeSO3])) were selected for experimental investigation. The experimental liquid-liquid extraction of pyrrole (taken as the model nitrogen compound) from n-hexadecane (the model fuel) was conducted at 298 K and 1 atm with feed concentrations of pyrrole ranging from 10 to 50 wt%, using either the two pure ILs or their mixtures with dimethylformamide or ethylene glycol. Moreover, the NRTL model was effectively used to correlate the experimental tie lines. This work shows that the use of a binary mixture of ILs with a conventional solvent results in good selectivity, but has a low capacity for extracting pyrrole compounds. On the other hand, using an IL-IL mixture exhibits good results for both capacity and selectivity. All the ternary systems tested showed positive slopes, indicating that the nitrogen compounds had a higher affinity for the IL and binary mixture extract phase. In fact, the extraction efficiency for all the systems shows promising results. This characteristic is advantageous, as it requires less solvent to remove nitrogen compounds.

Highly selective extraction of scandium(III) from rare earth elements using quaternary ammonium based ionic liquids: Experimental and DFT studies

Global demand for rare earth elements (REEs) is steadily increasing, emphasizing the necessity of effective extraction and recovery methods. Although REEs recovery from electronic waste using ionic liquid (IL) extractants offers an alternative solution to avoid potential adverse environmental impacts during traditional mining and processing, highly efficient and selective extraction is still essential. Especially, due to similarities with other REEs, recovery of scandium (Sc(III)) is confronting grand challenges. Herein, quaternary ammonium based ILs (QA-ILs), i.e., [N333 MeOAc][Tf2N] and [N444 MeOAc][Tf2N], have been successfully synthesized for selective Sc(III) extraction from other REEs under various conditions, e.g., initial acidity and IL concentration. Both ILs demonstrate superior selectivity for Sc(III) extraction from other REEs. Specifically, at pH 4.5 and 5, the extraction efficiency of Sc(III) using [N333 MeOAc][Tf2N] was 73.6 % and 83.4 %, respectively, while it was high up to 90.5 % and 95.9 %, respectively, using [N444 MeOAc][Tf2N]. Because of stronger hydrophobicity, [N444 MeOAc][Tf2N] exhibited a higher extraction efficiency. Furthermore, [N444 MeOAc][Tf2N] demonstrated a higher selectivity for Sc(III) as compared to other REEs, with high separation factor of 17 for Sc(III)/Lu(III) and Sc(III)/Yb(III). Additionally, the ILs can be recycled with a high stripping efficiency up to 86 % using 4 mol·L−1 H2SO4 solution. Density functional theory calculations further validated neutral exchange of Sc(III) in the neutral IL extraction process. This study presents a feasible solvent extraction system using novel QA-ILs for highly effective and selective Sc(III) extraction from waste streams.

Enhanced extraction of methanol and dimethyl carbonate by hydrogen bond breaking-reconstruction with deep eutectic solvents

The separation of methanol and dimethyl carbonate (DMC) is of great significance in industry. Extraction separation can be used for methanol-DMC separation due to simple operation and low energy consumption. The ionic liquid (IL) extractants can achieve good separation efficiency, but there is a problem of large loss of DMC entrainment. In this work, in order to reduce DMC entrainment, we introduced hydrogen bond donors into ILs to form deep eutectic solvents (DESs), so as to weaken the interaction between extractant and DMC. The characterization results indicated that the introduction of hydrogen bonding donors significantly reduces the viscosity of the system. Further extraction experimental results demonstrated that this strategy can effectively reduce the entrainment of DMC by 30 % while maintaining an extraction efficiency of up to 80 %. By conducting interaction energy calculations, electrostatic potential (ESP) charge analysis, interaction region indicator (IRI) analysis, and quantum theory of atoms in molecules (QTAIM) analysis for each system, the mechanism of hydrogen bond breaking and hydrogen bond reconstruction between DESs and components in methanol-DMC system was discovered, thus elucidating the mechanism of reducing DMC entrainment at the molecular level.
