DCB dissolution of iron oxides in aeolian dust deposits controlled by particle size rather than mineral species. [PDF]
Sci Rep, 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]
Nat CommunIn 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 ...

Accelerated dissolution of iron oxides in ice [PDF]
Atmospheric 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]
The 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 ...
