Electron transfer enhancing Fe(II)/Fe(III) cycle by sulfur and biochar in magnetic FeS@biochar to active peroxymonosulfate for 2,4-dichlorophenoxyacetic acid degradation

, 2021
A highly active mediator (magnetic FeS@biochar, MFB) for peroxymonosulfate (PMS) activation was prepared by employing FeSO4·7H2O and poplar sawdust as the precursor, for pesticides remediation in soil and groundwater. The magnetic FeS@biochar prepared at

Adsorption and reduction of Cr(VI) by a novel nanoscale FeS/chitosan/biochar composite from aqueous solution

, 2021
The purpose of this study was to synthesize FeS/chitosan/biochar composite (FSBC) to remove Cr(VI). Results indicate that the modification of FeS particles and chitosan to biochar provided large specific surface area and more active adsorption sites ...

Electronic Specific Heat of Dilute Alloys: Fe(Ti), Fe(V), Fe(Cr), Fe(Mn), Fe(Co), Fe(Ni), Fe(Al), Fe(Si), Fe(Mo), Fe(W), and Ag(Au)

Physical Review, 1966
A method of measuring simultaneously the low-temperature specific heat of three samples, typically one pure-metal sample and two alloys with 1 and 2% solute, is described. The procedure is used to determine the variation of the electronic-specific-heat coefficient $\ensuremath{\gamma}$ (the coefficient of the term linear in temperature) with ...

Mössbauer studies of FeBe, FeNb, FeRu, FeTe, and FeIr alloys

Physica Status Solidi (a), 1974
The isomer shifts, quadrupole splittings, and magnetic hyperfine splittings of iron in α-Fe–Be: FeBe5, α-Fe–Nb, γ-Fe–Nb, α-Fe–Ru, γ-Fe–Ru, FeTe2, α-Fe–Ir, and γ-Fe–Ir alloys are measured using the Mossbauer effect. Some of these studies were carried out as a function of temperature in the temperature range 60 to 300 °K.

Facile integration of FeS and titanate nanotubes for efficient removal of total Cr from aqueous solution: Synergy in simultaneous reduction of Cr(VI) and adsorption of Cr(III).

Journal of Hazardous Materials, 2020
In this study, a novel composite composed of iron monosulfide nanoparticles (FeS NPs) and titanate nanotubes (TNTs) was hydrothermally synthesized. Characterizations revealed the encapsulation and homogenous dispersion of FeS NPs into the interlayers of ...

Removal of hexavalent chromium using biogenic mackinawite (FeS)-deposited kaolinite.

Journal of Colloid and Interface Science, 2020
The biogenic mackinawite (FeS) is a promising remover for hexavalent chromium. However, FeS is susceptible to aggregation, affecting the removal efficiency of Cr(VI). To address the aggregation of FeS, kaolinite was selected as the stabilizer to disperse

Degradation of the β-blocker propranolol by sulfite activation using FeS

, 2020
A new advanced oxidation process, FeS-activated sulfite system, was firstly established to degrade β-blockers in water at near neutral pH. By choosing propranolol (PRO) as a model compound, the experimental conditions including FeS and sulfite doses ...
