Summary: This study systematically investigated the effect of NO3- on the degradation of TCE by S-ZVI and its mechanism. The results showed that NO3- did not affect the degradation pathway of TCE, but at high concentrations, it competed for electrons and led to an increase in the production of acetylene. Additionally, the presence of NO3- promoted the formation of Fe3O4, which improved the degradation efficiency of TCE.

Summary: This study investigated the feasibility of using zero-valent iron (ZVI) in a continuous-flow packed bed reactor for the effective remediation of 3-nitro-1,2,4-triazol-5-one (NTO). The ZVI-packed columns successfully reduced NTO to a safe product and the column treating acidic influent showed better performance than the column treating neutral influent. Reactivation using 1 M HCl restored the exhausted columns' NTO reducing capacity.

Summary: This study investigated the effect of hydrogenotrophic denitrification on cadmium (Cd(II)) removal and column life-span using hydrogen-autotrophic microorganisms and zero-valent iron (Fe-0) filled columns. The results showed that the nitrate-mediated bio-Fe-0 column had a higher Cd(II) removal efficiency and longer service life compared to the bio-Fe-0 and Fe-0 columns. This improvement was attributed to hydrogenotrophic denitrification, which caused more iron corrosion and more secondary mineral generation, providing more reaction sites for Cd(II) adsorption and immobilization. The distribution of reactive zone along the bio-Fe-0 column mediated by nitrate was found to be uneven, with the latter half part identified as a more active region for Cd(II) immobilization.

Summary: In this study, the mechanism of Cr(VI) contaminated aquifer remediation using nZVI@rGO was explored through experiments and characterization analysis. The results showed that the large reactive conjugated structure of rGO enhanced the electron transfer efficiency between Cr(VI) and nZVI@rGO, while the uniform accommodation of Cr(III) precipitates on rGO effectively retarded the surface passivation of nZVI.

Summary: The study found that using ZVI-containing biochar can effectively reduce nitrate contamination in groundwater, however, the ammonia formed during the reduction process remains in the aqueous phase, leading to no overall decrease in total nitrogen. Acid-washed zeolite can be used to adsorb the remaining ammonium and maintain an acidic pH for further nitrate reduction.

Summary: This study compared the performance of microscale zero-valent iron, autotrophic hydrogen bacteria, and their coupling system in remediating chlorinated aliphatic hydrocarbon-contaminated groundwater. The results showed that the mZVI-AHB and mZVI systems were more efficient in dechlorination, while the H2-AHB system exhibited higher selectivity in reducing nitrate. After considering factors such as degradation efficiency, reaction products, electron efficiency, and cost, the mZVI-AHB system showed higher potential in sustainable remediation.

Summary: In this study, a novel composite (nZVI@PBC) consisting of nanoscale zero-valent iron supported by polycaprolactone-modified biochar was synthesized to address the pollution problem of 1,1,1-trichloroethane (1,1,1-TCA) in groundwater. The composite coupled with Shewanella putrefaciens CN32 exhibited excellent removal performance for 1,1,1-TCA, with a removal rate of 82.98% within 360 h. The major improvement mechanisms include the nZVI-mediated chemical reductive dechlorination and the CN32-mediated microbial dissimilatory iron reduction.

Summary: This study used zero valent iron (Fe-0) for in-situ remediation of contaminated soil. The results showed that Fe-0 treatment reduced the levels of Cd and Zn in the soil and increased the biomass of soybean and rape. The separated iron-rich substances adsorbed Cd and Zn and generated new iron oxides. This study suggests the feasibility of Fe-0 for soil remediation, and the use of retrievable materials from soil for permanent pollutant removal should be considered in future remediation practices.

Summary: This study demonstrates the utility of synchrotron-based X-ray spectroscopic techniques in investigating the geochemistry of vanadium in ancient marine sediments. The results show that vanadium is primarily hosted by phyllosilicate-III and is strongly associated with potassium-rich clay minerals. The findings suggest that differentiating authigenic and detrital vanadium in ancient marine sediments may not be possible, which has implications for vanadium isotope system studies.

Summary: Sustainable management of organic biowaste and arable soil contamination by toxic elements is a concern. A pot trial was conducted to remediate As/Pb co-contaminated soil using chitin, crawfish shell biochar, crawfish shell powder, and CT-CSB composite. Results showed that the addition of amendments decreased Pb bioavailability, with CT-CSB treatment being the most effective. CSP and CSB increased soil available As concentration, while CT and CT-CSB treatments reduced it. CT addition enhanced soil enzyme activities, while CSB-containing treatments suppressed most enzymes. Bacterial abundance and composition in soil were altered by the amendments, and soil chemical properties were strong predictors of As/Pb availability. CT-CSB can potentially immobilize As and Pb and restore soil ecological functions.

Summary: Lithium (Li) is increasing in value due to its use in energy storage devices for electric vehicles. Seawater mining of Li is a sustainable alternative to conventional land mining. In this study, a hybrid nanomaterial, HMO@ZIF, was developed to selectively adsorb Li from seawater. The encapsulation of zeolitic imidazolate frameworks (ZIF) onto hydrogen manganese oxide (HMO) particles led to improved Li uptake through increased surface area, additional functional groups, and zinc ion intercalation.

Summary: Pesticides, such as fipronil, propyzamide, and flutriafol, have long lasting effects on non-target microorganisms. These pesticides affect soil microbial community structure, enzymatic activities, and abundance of key functional genes. Although the microbial community can recover from the pesticide effects, the persistent inhibitory effects on soil enzymatic activities indicate the lack of functional recovery.

Summary: This paper presents the use of synchrotron-based X-ray techniques to investigate the vanadium host phases in ancient marine sediments. The results show that vanadium is mainly present as vanadium (III) hosted by phyllosilicate. Strong associations between vanadium and potassium suggest that vanadium is hosted by potassium-rich clay minerals. Differentiating authigenic and detrital vanadium in ancient marine sediments is unlikely due to similar chemical speciation for both fractions.

Summary: In this work, a portable analytical system based on point discharge chemical vapor generation atomic emission spectrometry (PD-CVG-AES) coupling with gold filament enrichment was designed. The highly sensitive analysis of Hg2+ indirectly realized the detection of ascorbic acid (AA). The measurement is based on the fact that Ag+ can decrease the concentration of Hg2+ by forming Ag-Hg amalgam in the presence of the reductant SnCl2, while AA can pre-reduce Ag+ to Ag0, leading to the generation of silver nanoparticles (Ag NPs). The developed novel analytical strategy broadens the application of microplasma-based AES and offers a higher level of sensitivity compared to current AA detection techniques.
