Iron sulfide nanoparticles (nano-FeS) have shown great potential for in situ remediation of Cr(VI) pollution by reducing to the less soluble and toxic Cr(III). However, material oxidation that inevitably occurs during storage application alters its reactivity. Herein, we show partial nanoparticulate mackinawite (FeS) significantly enhances capability sequestering Cr(VI). Oxidation nano-FeS increases binding affinity Cr(VI), likely due preferential inner-sphere complexation oxyanions ferric...
Remediation of large and dilute plumes groundwater contaminated by oxidized pollutants such as chromate is a common difficult challenge. Herein, we show that in situ formation FeS nanoparticles (using dissolved Fe(II), S(-II), natural organic matter nucleating template) results uniform coating aquifer material to create regenerable reactive zone mitigates Cr(VI) migration. Flow-through columns packed with quartz sand are amended first an Fe2+ solution then HS– form nano-FeS on the sand,...
Mercury is a ubiquitous heavy-metal pollutant and poses serious ecological human-health risks. There an ever-growing demand for rapid, sensitive, selective detection of mercury in natural waters, particularly regions lacking infrastructure specialized analysis. Here, we show that sensor based on multi-emission carbon dots (M-CDs) exhibits ultrahigh sensing selectivity toward Hg(II) complex environmental matrices, tested the presence range environmentally relevant metal/metalloid ions as well...
The effect of hydrophilicity or hydrophobicity polyelectrolyte on the interaction between and oppositely charged surfactants was investigated by using coarse-grained molecular dynamics simulations. aggregation hydrophilic is significantly different from that hydrophobic polyelectrolyte. complexes evolve "bottle brush", through "necklace", then to micelle. However, rod-like micelle, in which wraps around micelle surface, only appears system. For system, spherical formed, penetrates into core...
Most soil remediation studies investigated single contaminants or multiple of the same type. However, in field conditions, soils are often contaminated with potentially both toxic metals and organic pollutants, posing a serious technical challenge. Here, batch experiments were conducted to evaluate performance combining situ solidification/stabilization (ISS) chemical oxidation (ISCO) for simultaneous removal aniline (1000 mg/kg) Cd (10 mg/kg). All four tested ISS amendments, especially...
A novel composite of montmorillonite-supported carboxymethyl cellulose-stabilized nanoscale iron sulfide (CMC@MMT-FeS), prepared using the co-precipitation method, was applied to remediate hexavalent chromium (Cr(VI))-contaminated soil. Cr(VI)-removal capacity increased with increasing FeS-particle loading. We tested efficacy CMC@MMT-FeS at three concentrations FeS: 0.2, 0.5, and 1 mmol/g, hereafter referred as 0.2 CMC@MMT-FeS, 0.5 1.0 respectively. The soil Cr(VI) concentration decreased by...
Conventional approaches for in situ remediation of mercury (Hg)-contaminated soils and sediments rely mostly on precipitation or adsorption. However, this can generate Hg-rich surfaces that facilitate microbial production methylmercury (MeHg), a potent, bioaccumulative neurotoxin. Herein, we prove the concept risk methylation be effectively minimized by adding sulfur-intercalated layered double hydroxide (S-LDH) to Hg-contaminated soils. Hg bound S-LDH has minimal potential when incubated...
Based on the perspective of new structural economics, this study builds a theoretical framework human capital structure and environmental pollution. Human pollution has different manifestations at stages development, effect based follows Kuznets curve. Using multinational panel data (1990–2015) provincial for China (2004–2020), examined dynamic relationship between upgrading by introducing an interaction term economic development level, applying random-effect, fixed-effect models, model...
