Biogeochemical cycling of iron is crucial to many environmental processes, such as ocean
productivity, carbon storage, greenhouse gas emissions and the fate of nutrients, toxic …

Reduction–oxidation (redox) reactions underlie essentially all biogeochemical cycles. Like
most soil properties and processes, redox is spatiotemporally heterogeneous. However …

The amount and composition of root exudates—low-molecular-weight carbon compounds
released from living plant roots into soil—are expected to shift under global change, and a …

Anaerobic oxidation of methane (AOM) is crucial for controlling the emission of this potent
greenhouse gas to the atmosphere. Nitrite-, nitrate-, and sulfate-dependent methane …

In this study, we construct a surface Fenton system with hydroxylamine (NH2OH), goethite (α-
FeOOH), and H2O2 (α-FeOOH–HA/H2O2) to degrade various organic pollutants including …

Activation of peracetic acid (PAA) with iron species is an emerging advanced oxidation
process (AOP). This study investigates the use of the chelating agent picolinic acid (PICA) to …

Phosphate recovery from sewage sludge is essential in a circular economy. Currently, the
main focus in centralized municipal wastewater treatment plants (MWTPs) lies on struvite …

Wetlands cover a small portion of the world, but have disproportionate influence on global
carbon (C) sequestration, carbon dioxide and methane emissions, and aquatic C fluxes …

The Fenton system generates reactive species with high oxidation potential such as
hydroxyl radicals (HO•) or ferryl via the reaction between Fe (II) and H2O2. However, a …

The reaction between dissolved sulfide and synthetic iron (oxyhydr) oxide minerals was
studied in artificial seawater and 0.1 M NaCl at pH 7.5 and 25° C. Electron transfer between …
