Summary: This study introduces a novel process for synthesizing zero-valent iron/biochar using wood waste and iron mud, and highlights the superior performance of Fe-0-BC-1200 in removing rhodamine B due to the generation of more Fe-0 particles at higher temperatures. The removal mechanism involves both physical adsorption of biochar and redox reactions of Fe-0, with the additional benefit of copper reduction in the iron mud promoting the oxidation of iron and degradation of RB.

Summary: This study explored a low-energy and low-cost method for the preparation of zero-valent iron (ZVI) materials using biomass, such as corn straw, wheat straw, rice husk, pine wood and coffee grounds, to reduce iron oxide in red mud. The results showed that biomass could efficiently reduce iron oxide to ZVI at a temperature 100 degrees Celsius lower than the conventional method. The ZVI material also exhibited good removal effect on gentian violet and methylene blue, suggesting its potential for pollutant treatment.

Summary: Red mud, a polluting waste product emitted from the aluminum production industry, poses a potential threat to the environment due to its high alkalinity and complex chemical composition. In this study, granular porous zero valent iron (ZVI) adsorption reaction materials (Fe/GSBR) were prepared using red mud, straw, and bentonite. The optimal preparation conditions were determined through response surface analysis, and the properties of Fe/GSBR were characterized to demonstrate its porous and ZVI material nature. Additionally, the regeneration properties and toxic leaching of the materials were evaluated to ensure their environmental safety during use.

Summary: In this study, the removal of hexavalent chromium (Cr(VI)) and Trichloroethylene (TCE) by rice straw pyrolysis biochar supported nanoscale zero-valent iron (nZVI) was investigated. The results showed that biochar supported nZVI effectively removed Cr(VI) and TCE in single pollutant system, but mutual inhibition occurred when both contaminants were present. Therefore, the mutual inhibition effect should be evaluated in the remediation of combined contaminated groundwater.

Summary: This study improved the reactivity of zero-valent iron (ZVI) towards tetracycline (TC) degradation by using biogenetic sulfidation and biochar loading. Biochar provided more attachment sites and alleviated ZVI agglomeration. Biogenetic sulfidation inhibited ZVI surface passivation. The formation of Fe(II/III)-TC complexes promoted TC degradation.

Summary: In this study, nZVI-modified low-temperature biochar was used to adsorb Sb(III) from water. The adsorption capacity and speed of nZVI-BC were better than those of BC, and the best adsorption effect was observed for 4nZVI-BC. XRD, FTIR, and XPS characterization demonstrated that the adsorption mechanism predominantly included redox reactions, complexation, and electrostatic interactions. The experiment also showed that 4nZVI-BC had good performance in repeated use for Sb(III) adsorption.

Summary: Copper/carbon catalysts exhibit different pathways in peroxide activation depending on the electron-transfer regime, but the trigger for this transition is unclear. This study reveals that Cu species in sub-nanometre particles (SNPs) have an electrophilic nature, while Cu nanoclusters have a nucleophilic nature. The switch between nucleophile/electrophile nature leads to distinct catalytic mechanisms in activating peroxymonosulfate. The study demonstrates the regulable electroactive nature of carbon-supported Cu sites through scaling modulation and defect engineering.

Summary: The use of functionalized biochar amendments can reduce the accumulation of potentially toxic elements (PTEs) in rice grains. Specifically, silicon (Si)-rich and phosphorus (P)-rich biochars can decrease the concentration of arsenic (As) in rice grains, while iron-modified biochars can enhance rice grain yield. Additionally, P-rich biochar can increase the activity of beneficial bacteria in the soil and decrease lead (Pb) concentration in rice grains. However, iron-modified P-rich biochar can increase cadmium (Cd) and Pb concentration in rice grains.

Summary: Rapidly changing fashion trends have resulted in a large amount of textile waste globally. Textile waste, which consists of various substances, poses challenges for recycling due to its inhomogeneity and complexity. Pyrolysis, a thermochemical process, can upcycle textile waste into value added products. This article provides a systematic review of pyrolysis processes for upcycling textile waste, discussing challenges and recommending future research needs. Despite these challenges, pyrolysis can be an effective end-of-life option for textile waste with continuous research and development.

Summary: In this study, the interaction between microplastics and biochar during environmental aging was investigated. It was found that early-stage interactions of microplastics and biochar could promote the release of dissolved organic matter (DOM) from biochar, while their long-term interactions resulted in the sorption of hydrophobic and small molecules of microbial byproduct-like DOM. Early-stage interactions also promoted the sorption of organic contaminants, but this promotion was no longer observed after aging due to the influence of heterogeneous aggregation.

Summary: To assess the pulmonary toxicity of polystyrene nanoparticles (PSNPs) and reduce assessment error, a Transwell-based bronchial epithelial cell exposure system was established. The system was more sensitive than submerged culture in detecting PSNPs toxicity. PSNP adhesion, ingestion, and accumulation in the cytoplasm of BEAS-2B cells induced oxidative stress, inhibited cell growth, and triggered apoptosis and autophagy. PSNPs also increased the expression of inflammatory factors in noncytotoxic doses and induced apoptosis and autophagy in cytotoxic doses, suggesting their harmful effects on human pulmonary health.

Summary: In this study, a sequential and scalable hydro-oxygen repair (HOR) route was proposed for closed-loop recycling of spent LiFePO4 batteries. The route involves steps such as cathode electrode separation, oxidative extraction of lithium, and restoration of lithium iron phosphate crystals. The HOR route demonstrated efficient separation and extraction of materials, and the regenerated crystals showed comparable electrochemical capacity to commercial cathode materials. Life cycle assessment showed significant reduction in carbon emissions and smog release, contributing to a circular economy and decarbonization.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
