Soil water serves as a crucial factor that restricts the mass transfer of contaminants. The thermal enhanced soil vapor extraction (T-SVE) is an effective technique for treating low-permeability contaminated soils. This paper investigated the removal and migration characteristics of diesel in low-permeability contaminated soils considering water competitive adsorption from a new insight of low-field nuclear magnetism resonance (LF NMR). In this study, a new method for simultaneous testing contaminant concentration and water content was proposed. The results shows that the removal efficiency of diesel is significantly lower than that of soil water during the dynamic extraction process. The diesel re-adsorption is a primary mechanism leading to the low remediation efficiency in low-permeability contaminated soils. Due to the competitive adsorption advantage of water molecules, the phenomenon of diesel re-adsorption was observed below 7 % water content. An optimal water content range of 7 %-16 % was proposed, which can provide optimized parameter for SVE remediation. After the T-SVE process with heating to 250℃, diesel can be removed with a removal rate of 99.8 %. The removal process of different carbon number groups in diesel conforms to an exponential decay kinetic model. Among them, the C10-C12 are mostly desorbed by SVE process. The C13-C20 and C21-C24 are removed during the T-SVE process at 150℃ and 250℃, respectively. In addition, the T1-T2 relaxation behaviors provide insights into the typical migration characteristic of diesel and soil water, including the dynamic migration of diesel, free water and bound water.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"14 2","pages":"Article 121239"},"PeriodicalIF":7.2,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145981771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The composites were synthesized by a hydrothermal route with 30, 50, and 70 wt% of HKUST–1(Cu/Fe) incorporated into BiVO₄ and subsequently annealed at 400 °C in air. The synthesized materials were characterized using thermogravimetric analysis (TGA), X–ray diffraction (XRD), X–ray photoelectron spectroscopy (XPS), UV–Visible diffuse reflectance spectroscopy (UV–Vis DRS), photoluminescence spectroscopy (PL), Mott–Schottky/EIS techniques, Raman spectroscopy, and nitrogen physisorption. The incorporation of the CuO–Fe derived HKUST–1(Cu/Fe) into BiVO₄, with monoclinic crystalline structure, preserved visible light activity (Eg = 2.09 – 2.28 eV) and improved the textural properties by increasing the surface area (from 1.25 to 7.89 m² g^–1) and pore volume (from 0.011 to 0.484 cm³ g^–1) in the composites; and also favored the formation of oxygen vacancies, which enhanced the photocatalytic activity compared with that of BiVO₄. The photocatalytic degradation of AMX was improved at pH 7 by using the composite with 50 wt% HKUST–1(Cu/Fe) in BiVO₄, reaching 92.92 % in 3 h, compared with 75.59 % for BiVO₄. The degradation by–products were monitored using GC–MS and ion chromatography (IC), which confirmed the formation of acetic, maleic, and fumaric acids at the end of the process. QSAR (Quantitative Structure–Activity Relationship) analysis indicated that these compounds have low acute and chronic toxicity. The inactivation of <em>Staphylococcus aureus</em> and <em>Escherichia coli</em> with the effluent derived of AMX photocatalytic oxidation by H1(Cu/Fe)50Bi under UV–Vis irradiation (16.4 % for <em>E. coli</em> and 52.2 % for <em>S. aureus</em>) and simulated sunlight exposure (10.9 % <em>E.coli</em> and 42.4 % for <em>S. aureus</em>), indicated the reduction of its antimicrobial activity. Additionally, the photocatalytic material remained stable over three reuse cycles for AMX degradation. The study conducted in the presence of sequestering agents for reactive oxygen species indicated that holes were the primary species responsible for AMX degradation.

Results showed that gill (-121.121 kJ/mol) and liver (-118.234 kJ/mol) had high bioaccumulation levels, and brain (-84.640 kJ/mol), intestine (-85.900 kJ/mol) and muscle (-86.311 kJ/mol) tissues had low bioaccumulation levels.

The results showed that FLCMs with a greater number of aromatic rings and atoms tend to exhibit stronger enrichment potential, leading to higher binding affinity in zebrafish tissues. In addition, POPs that share structural features with FLCMs display tissue-specific accumulation patterns similar to those observed for FLCMs, with both groups preferentially accumulating in the gill and liver of zebrafish. When the number of aromatic rings and atoms of FLCMs increased, their bioaccumulation effect in zebrafish tissues was stronger.

Achieving high-efficiency manure valorization while simultaneously mitigating pollution and maximizing resource recovery remains a central challenge in environmental engineering and sustainable agriculture.

Conventional composting efficiently transforms organic matter into humic acids (&gt;30 % content) but is limited by prolonged processing (30–60 days) and substantial greenhouse gas emissions (0.3–0.8 kg N₂O/t). HTC offers rapid conversion (4–6 h) and high-energy hydrochar (18–25 MJ/kg), yet is hindered by severe process water contamination (COD: 20,000–80,000 mg/L). Multi-scale analyses reveal that: (i) compost-derived humic functional groups (-COOH, -OH) enhance HTC reactivity at the molecular level; (ii) coupling “HTC pretreatment + composting post-treatment” increases overall efficiency by 40 % and reduces the carbon footprint to 15 kg CO₂-eq/t; and (iii) intelligent process control enables nitrogen and phosphorus recovery rates above 90 %. The proposed “pollution control–resource recovery–carbon neutrality” framework substantially lowers environmental risks while enabling simultaneous energy recovery and nutrient recycling.
