Elucidating Phosphate and Cadmium Cosorption Mechanisms on Mineral Surfaces with Direct Spectroscopic and Modeling Evidence Open
The simultaneous sorption of cations and anions at the mineral-water interface can substantially alter their individual sorption characteristics; however, this phenomenon lacks a mechanistic understanding. Our study provides direct spectro…

Cadmium Isotope Fractionation during Adsorption onto Edge Sites and Vacancies in Phyllomanganate Open
Cadmium (Cd) geochemical behavior is strongly influenced by its adsorption onto natural phyllomanganates, which contain both layer edge sites and vacancies; however, Cd isotope fractionation mechanisms at these sites have not yet been addr…

Enhanced efficiency of refractory organic pollutant degradation over a wide pH range by peroxymonosulfate activated by cobalt-doped FeS Open
A series of cobalt-doped FeS (x% Co-FeS) nanoparticles prepared using a hydrothermal method were introduced as catalysts to generate powerful radicals from peroxymonosulfate (PMS) for endocrine disrupter bisphenol S (BPS) degradation in wa…

Adsorption Mechanisms of Glyphosate on Ferrihydrite: Effects of Al Substitution and Aggregation State Open
Ferrihydrite is one of the most reactive iron (Fe) (oxyhydr)oxides in soils, but the adsorption mechanisms of glyphosate, the most widely used herbicide, on ferrihydrite remain unknown. Here, we determined the adsorption mechanisms of glyp…

Chemical speciation of phosphorus in farmland soils and soil aggregates around mining areas Open
Phosphorus (P) speciation determines its bioavailability, mobility, and environmental risk in soils. Farmland soils around mining areas are worldwide distributed, yet the P speciation in such soils remains poorly understood. In this study,…

Transformation of zinc oxide nanoparticles in the presence of aluminum oxide with pre-sorbed phosphorus ligands Open
Naturally occurring oxides could react with zinc oxide (ZnO) nanoparticles (NPs) and then change its transformation and toxicity to ecological receptors. The reaction may be affected by a variety of environmental factors, yet the relevant …

Molecular-Scale Understanding of Sulfate Exchange from Schwertmannite by Chromate Versus Arsenate Open
Schwertmannite effectively sorbs chromate (Cr(VI)), yet the sorption mechanisms remain elusive. We determined the Cr(VI) sorption mechanisms on schwertmannite at pH 3.2 and 5 using combined macroscopic sorption experiments with molecular-s…

Synergistic effect of Co(II) doping on FeS activating heterogeneous Fenton processes toward degradation of Rhodamine B Open
Iron-based heterogeneous Fenton systems have been widely proposed for recalcitrant contaminants degradation. However, low efficiency of H2O2 decomposition and Fe(II)/Fe(III) recycling quite limited their applications. In this work, Co-dope…

Coupled morphological and structural evolution of δ-MnO<sub>2</sub> to α-MnO<sub>2</sub> through multistage oriented assembly processes: the role of Mn(<span>iii</span>) Open
δ-MnO2 transforms to α-MnO2 through a multistage oriented assembly process which is induced by Mn(iii).
View article: Phosphate Sorption Speciation and Precipitation Mechanisms on Amorphous Aluminum Hydroxide
Phosphate Sorption Speciation and Precipitation Mechanisms on Amorphous Aluminum Hydroxide Open
Aluminum (Al) oxides are important adsorbents for phosphate in soils and sediments, and significantly limit Phosphate (P) mobility and bioavailability, but the speciation of surface-adsorbed phosphate on Al oxides remains poorly understood…
