Enhanced removal of As(III)/(V) from water by simultaneously supported and stabilized Fe-Mn binary oxide nanohybrids
Zimo Lou,Zhen Cao,Jiang Xu,Xiaoxin Zhou,Jin Zhu,Xue Liu,Shams Ali Baig,Junliang Zhou,Xinhua Xu +8 more
TL;DR: In this article, reduced graphene oxide (RGO) and different stabilizers (hexadecyltrimethylammonium bromide, starch, and carboxymethyl cellulose) were applied to simultaneously support and stabilize Fe-Mn binary oxide (FeMnOx) nanohybrids, and enhanced removal of As(III)/(V) from water was achieved.

Antimony and arsenic speciation, redox-cycling and contrasting mobility in a mining-impacted river system
Scott G Johnston,William W. Bennett,Nicholas J. C. Doriean,Kerstin Hockmann,Niloofar Karimian,Edward D Burton +5 more
TL;DR: The Macleay River in eastern Australia is severely impacted by historic stibnite- and arsenopyrite-rich mine-tailings, and localised redox-driven shifts in speciation of both elements strongly influence their respective mobility and partitioning.

Chitosan functionalized iron nanosheet for enhanced removal of As(III) and Sb(III): Synergistic effect and mechanism
TL;DR: In this article, a natural polysaccharide chitosan (CS) functionalized iron nanosheet using an in-situ doping method was designed, aiming to attract neutral trivalent arsenic (As) and antimony (Sb) from aqueous solution.

Mechanisms of Arsenic Adsorption on Amorphous Oxides Evaluated Using Macroscopic Measurements, Vibrational Spectroscopy, and Surface Complexation Modeling.
TL;DR: In this study in situ Raman and Fourier transform infrared (FTIR) spectroscopic methods were combined with sorption techniques, electrophoretic mobility measurements, and surface complexation modeling to study the interaction of As(III) and As(V) with amorphous oxide surfaces.
Journal ArticleDOI
The chemistry and behaviour of antimony in the soil environment with comparisons to arsenic: A critical review
TL;DR: Characteristics of the Sb soil system are reviewed, with an emphasis on speciation, sorption and phase associations, identifying differences between Sb and As behaviour.

Arsenic adsorption onto iron oxide-coated cement (IOCC): Regression analysis of equilibrium data with several isotherm models and their optimization
TL;DR: In this article, the authors examined the equilibrium sorption of arsenic (III and V) from aqueous environment onto iron oxide-coated cement (IOCC) at 288, 298 and 308 K, and determined the equilibrium Sorption isotherms.

Antimony pollution in China.
TL;DR: The local environments around Sb mining and smelting areas were seriously contaminated and plants growing in these contaminated soils accumulated high levels of Sb and exceeded the tolerable concentration, thus threatening the health of local inhabitants.

Sorption of Sb(III) and Sb(V) to goethite: influence on Sb(III) oxidation and mobilization.
TL;DR: The results show that both Sb(III) and Sb (V) form inner-sphere surface complexes at the goethite surface, and adsorption of Sb on Fe hydroxides over a wide pH range may be a major pathway for the oxidation and release of S b(V).
