DCB dissolution of iron oxides in aeolian dust deposits controlled by particle size rather than mineral species [PDF]

open access: yesScientific Reports, 2022
Dithionite-citrate-bicarbonate (DCB) treatment is a classical method for removing iron oxides from soil. The DCB-induced dissolution effects on iron oxides are controversial.

Unraveling iron oxides as abiotic catalysts of organic phosphorus recycling in soil and sediment matrices [PDF]

open access: yesNature Communications
In biogeochemical phosphorus cycling, iron oxide minerals are acknowledged as strong adsorbents of inorganic and organic phosphorus. Dephosphorylation of organic phosphorus is attributed only to biological processes, but iron oxides could also catalyze ...

The influence of Shewanella oneidensis MR-1 on the transformation of iron oxides and phosphorus in a red soil

open access: yesSoil and Water Research, 2022
In this study, Shewanella oneidensis MR-1, an iron (Fe)-reducing bacterium, was inoculated to a red soil, which was then incubated. Soil samples were taken regularly to analyse the variation of iron oxides and phosphorus (P) fractions. The results showed

Accelerated dissolution of iron oxides in ice [PDF]

open access: yesAtmospheric Chemistry and Physics, 2012
Iron dissolution from mineral dusts and soil particles is vital as a source of bioavailable iron in various environmental media. In this work, the dissolution of iron oxide particles trapped in ice was investigated as a new pathway of iron supply.

Iron oxides in the cryoconite of glaciers on the Tibetan Plateau: abundance, speciation and implications [PDF]

open access: yesThe Cryosphere, 2018
Cryoconite is a mixture of impurities and ice visually represented by dark colors present in the ablation zone of glaciers. As an important constituent of light-absorbing impurities on the glacier surface, iron oxides influence the radiative ...

Synergistic Ti-Fe Oxides on Fishbone-Derived Carbon Sulfonate: Enhanced Styrene Oxidation Catalysis

open access: yesIndonesian Journal of Chemistry, 2023
Fishbone-derived carbon sulfonate, modified through incipient wetness impregnation with titanium tetraisopropoxide and iron nitrate salts, displays catalytic activity in the oxidation of styrene with hydrogen peroxide (H2O2) as an oxidant.
