Our study investigated the feasibility of solvent extraction for the separation of impurities, specifically aluminum (Al), copper (Cu), and iron (Fe) from simulated leachate with similar composition to real pregnant leach solution (PLS) obtained after the bioleaching of spent lithium-ion batteries (LIBs). The Fe2+ in the Fe-rich PLS was oxidized to Fe3+ by addition of H2O2. Subsequently, Fe3+, Al3+, Cu2+, and Mn2+ were extracted at pH 4.0 using 20 % di-(2-ethylhexyl) phosphoric acid (D2EHPA) as the extractant. At this pH, 99.99 % of Al3+ and Fe3+, 93 % of Cu2+, and 83 % of Mn2+ were successfully extracted. Co-extracted Co2+ was recovered through a two-stages scrubbing process, where it was replaced with Mn2+ using a MnSO4 solution at an O/A ratio of 1:1. Finally, Al3+, Cu2+, and Mn2+ were stripped with 5 M H2SO4, and 99 % Fe3+ was separated by stripping with 100 % aqua regia. Our study presents an approach for effectively separating valuable metals and impurities, particularly Fe, by optimizing the extraction, scrubbing, and stripping stages of solvent extraction for PLS treatment. Moreover, this study emphasizes the need for further research on the pre-separation of Fe and the development of novel extractants and solvents to enhance the treatment of Fe-rich PLS after bioleaching.

Composite materials have gained significant attention due to their ability to combine distinct characteristics from two or more components, resulting in improved performance for various applications. This review paper examines the advancements made in the integration of two promising materials, biochar and graphene oxide (GO), in composite structures. Biochar, derived from biomass, offers unique physicochemical properties, while GO possesses a 2D structure with enhanced porosity and tunable electrical properties. However, there is a significant research gap in systematically understanding the combined effects of biochar and GO in composite materials, particularly concerning their synthesis techniques, environmental impact, and performance in diverse applications. This review addresses this gap by providing a comprehensive analysis of the state-of-the-art methodologies for synthesizing biochar-GO composites, their multifunctional properties, and their potential applications. Notably, biochar-GO composites exhibit exceptional efficiency in adsorbing heavy metal ions and organic contaminants due to their enhanced surface area and functional groups. The adsorption mechanisms involve a variety of physical and chemical interactions, leading to superior affinities compared to individual materials. Furthermore, biochar-GO composites demonstrate remarkable potential for utilization in electrochemical applications, serving as electrodes for supercapacitors and microbial fuel cells. These multifunctional materials show immense potential in tackling water pollution issues and promoting sustainable approaches. This review provides extensive insights into the synthesis techniques, properties, and applications of biochar-GO composites, highlighting their remarkable versatility as sustainable materials.

This work addresses the ozonation, photolysis, and photolytic ozonation of metronidazole (MTZ), a widely used antibiotic frequently detected in urban wastewater. A UVA source emitting radiation between 300 and 400 nm was utilized. The presence of scavengers such as t-butanol and sodium azide confirmed the role of hydroxyl radicals in both ozonation and photolysis processes. Conversely, singlet oxygen did not influence the photolytic processes. The average quantum yields of MTZ and ozone were determined to be 1.2 × 10−3 and 0.72 mol/Einstein, respectively, for the 300–400 nm wavelength range. In direct MTZ photolysis, a stoichiometric ratio of 0.34 mol of hydroxyl radicals formed per mol of photolyzed MTZ was observed. However, the effects of hydroxyl radicals on the MTZ photolytic rate were only significant after 45 min of reaction time. Using rate constant data from literature and quantum yields calculated in this study, a kinetic model for both MTZ ozonation and photolytic ozonation was proposed, enabling the prediction of MTZ conversion and degradation rates. This model includes three intermediate compounds that also consume ozone and hydroxyl radicals. The results show that experimental and calculated concentrations of MTZ are within an error margin of less than 14 % in all cases.

Graphite membranes have gained attention in membrane technology for gas separation due to their high stiffness, strength, and stability in corrosive and high-temperature environments. Graphite exists naturally in geologic media and can also be prepared by synthetic processes. In- situ hydrogen (H2) production in petroleum reservoirs or H2 storage in depleted gas reservoirs results in contamination with CH4 and CO2. To address the separation challenge at the surface, a sustainable downhole wellbore membrane must be available to separate H2, leaving behind CO2 and other gases to improve operational economics. Currently, there are no studies in the literature on the self-diffusivity of gases (CO2, H2, and CH4) in graphite as a function of pore size. To overcome time constraints in diffusivity experiments, this work utilized mathematical models and molecular simulations to delineate the self-diffusivity of gases in graphite of different pore sizes.
To acknowledge subsurface operational conditions during in situ hydrogen production, we considered a temperature of 360 K and a wide pressure spectrum from 2 MPa to 21 MPa. In this study, we explored the diffusive nature of H2, CH4, and CO2 gases in different nanopore-sized graphite using analytical and molecular simulation approaches. We validated the results by presenting unrestricted case density calculations. First, effective diffusivity was calculated using the mean free pore path, followed by gas adsorption at high pressures (10–21 MPa) and a temperature of 350 K. The study utilized theoretical models and molecular dynamics (MD) simulations to determine the self-diffusivity of gases in graphite systems with various structures.

A liposome-based nitrite biosensor was prepared by encapsulating the nitrite reductase NirB enzyme and embedding the nitrite-specific NirC channels in the liposome structure. The proteoliposomes were coated on the glassy carbon electrode modified with the multi-walled carbon nanotube/chitosan matrix. The absence of channels in the liposome structure inhibits the generation of typical reduction peaks upon the addition of nitrite suggesting that ion channels are necessary for the passage of charged ions into the liposome. The response of the NirB and NirC incorporated liposome-based biosensor (CBLip/MWCNTs/CHIT/GC electrode) to the nitrite is shown to be fast and reproducible. The electrode shows a linear response between 1–500 µM nitrite concentrations. The sensitivity of the CBLip/MWCNTs/CHIT/GC electrode was 707 mA.M−1.cm−2, lower than that of the unentrapped NirB-loaded electrode (1131 mA.M−1.cm−2). While the electrode prepared with the unentrapped enzyme lost its activity in 30 days, entrapment of the enzyme in the liposome preserved the electrode activity by 55 %. The electrodes showed unexpected oxidation responses against high concentrations of sulfate and formate, the incorporation of NirC channels contributed to increasing the specificity of the electrode towards nitrite in the presence of these ions. The use of substrate-specific membrane channels in liposome-based biosensors was achieved for the first time in the present study.

Endocrine disrupting chemicals (EDCs) are pollutants found in low concentrations but with high toxicity. Therefore, selecting suitable methods to manage and mitigate the risks associated with EDCs is of utmost practical importance. This study delves into the removal mechanism of EDCs using chemically modified biochar, summarizing the sources, classifications, removal technologies of EDCs, and biochar modification methods. Furthermore, it examines the synergistic mechanism of chemically modified biochar in mediating EDCs removal. The results of 32 chemical modification experiments summarized indicate that chemical modification alters the specific surface area, pore size, and O/C ratio of biochar. Notably, 78.1 % of the studies found that chemically modified biochar enhanced the specific surface area. In the actual removal process of pollutants by biochar, multiple interactions are involved, including π-π bond interactions, hydrogen bond interactions, electrostatic interactions, hydrophobic interactions, and pore filling. These mechanisms typically function in combination rather than in isolation. The 20 studies reviewed demonstrated that the removal rate of EDCs by chemically modified biochar ranged from 63.3 % to 100 %. Furthermore, this article suggests future research for the removal of EDCs using chemically modified biochar, to offer environmentally friendly solutions for EDCs removal in water and serve as a reference for efficient removal.

The polyol method has been the most commonly used technique for fabricating silver nanowires (Ag NWs), wherein additive reagents facilitate precise control over their morphology. In this work, we introduced a straightforward approach to synthesize Ag NWs with minimal impurities and uniform diameter by using hot injection method. The underlying mechanism and final product are evaluated, and the scalable process was optimized to achieve a high yield (∼87.8%). It was found that the hot injection of a Ag precursor at 170 °C significantly accelerated the reduction of Ag ions. The issue of the uniformity of Ag NWs was addressed by adding an organic halide to control the nucleation rate of Ag. The resulting Ag NWs solution was used to impregnated cellulose paper, forming an enhanced electrical network compared to other substrates. Given the low commercial cost of paper, this approach holds significant potential for widespread use in disposable electrodes. Furthermore, after subjecting the fabricated paper electrodes to various forms of damage, the connected LED bulbs consistently maintained their brightness. This demonstrates the network stability and suitability of these electrodes for flexible applications.

The design of superhydrophobic materials based on zeolite imidazolate frameworks (ZIF) has attracted considerable attention due to their exceptional chemical stability, high specific surface area, and environmental friendliness. However, research in the fields of anti-corrosion and anti-icing remains in its infancy, and the mechanical stability of reported ZIF-based superhydrophobic surfaces is generally poor. In this study, we synthesized ZIF-8@PDA materials in an aqueous system and followed with stearic acid (STA) modification to achieve low surface energy, resulting in ZIF-8@PDA@STA. Subsequently, we applied a spray-coating method to sequentially construct WPU and ZIF-8@PDA@STA layer on aluminum alloy substrates, achieving a ZIF-8@PDA@STA/WPU superhydrophobic coating with exceptional mechanical stability. This coating retained its superhydrophobicity even after 5600 cm of abrasion distance. Furthermore, results from surface wettability, electrochemical and anti-icing tests demonstrated that the coated aluminum alloy exhibited excellent interfacial non-wetting, self-cleaning, anti-fouling, and significantly enhanced corrosion resistance and delayed icing properties. Additionally, the facile preparation of this coating on various substrates facilitates the large-scale application of such materials. The construction of this multifunctional ZIF-8 based superhydrophobic coating is expected to greatly expand the application of ZIF materials across diverse fields.

Biowaste has become a serious problem that can lead to serious environmental pollution and waste of resources if not handled properly. Waste materials are often high in proteins, which are easily extracted and hydrolyzed to provide an adequate quantity of amino acids. This indicates that biowastes can be used as green and efficient corrosion inhibitors (CIs). This work aimed to prepare fish waste extract (FWE) by acid hydrolysis with alkaline leaching using fish waste as the raw material. The results of the characterization analysis identified the presence of 17 amino acids, with Leucine, Phenylalanine, Methionine, and Alanine being the most abundant. FWE was then tested as a corrosion inhibitor (CI) for carbon steel in 0.5 mol/L H2SO4. Further, the effect of KI on the corrosion inhibition performance of FWE for carbon steel in 0.5 mol/L H2SO4 was systematically investigated by the weight loss method, electrochemical method, and surface analysis. The maximum corrosion inhibition efficiencies were 88.7 % and 63.9 % for the FWE and KI alone, and 97.10 % for the combination of FWE and KI. The synergistic coefficient study confirmed that the synergistic coefficients of the FWE and KI exceeded 1 across all concentration conditions, indicating a synergistic effect between them. The surface analysis results showed that the deterioration of carbon steel after adding the compounded CI was mild, and pitting and crevice corrosion was not observed. Theoretical calculations revealed the active reaction sites of four major amino acid molecules via quantum chemical and molecular dynamics simulations. The effect of different types of side chains and heteroatoms of amino acid molecules on their corrosion inhibition performance was elucidated to provide theoretical guidance for designing biowaste CIs.

The emission of nitrogen oxides (NOx), volatile organic compounds (VOCs), and carbon dioxide (CO2) is a significant contributor to air pollution and global warming, negatively affecting both the environment and human health. Photocatalysis has emerged as an effective technology for eliminating the aforementioned species from waste gases. Layered double hydroxides (LDHs) have attracted increasing attention for their potential as the photocatalysts in gaseous pollutant and CO2 abatement reactions, relying on the advantages including earth abundance, easy fabrication, and low cost. This review provides a comprehensive summarization of recent progresses on the photocatalytic removal of NOx, VOCs, and CO2 using the LDHs-based materials. Simply put, the fundamentals of LDHs such as the crystal structures and the relevant synthesis methods were introduced at first. As activity and selectivity are recognized as the key properties for evaluating these catalysts, the advances in enhancing these properties were summarized and discussed in the subsequently sections. Furthermore, mechanisms of NOx oxidation, VOCs degradation, and CO2 reduction were also elucidated from a microscopic perspective. Finally, this review emphasizes the directions for improving the photocatalytic activity of the LDHs-based photocatalysts, along with the need to investigate the simultaneous removal of multi-pollutants and the catalysts’ gas component adaptability.
