Geobatteries in environmental biogeochemistry: Electron transfer and utilization

Environmental Science and Ecotechnology, Год журнала: 2024, Номер 22, С. 100446 - 100446

Опубликована: Июль 2, 2024

The efficiency of direct electron flow from donors to acceptors in redox reactions is significantly influenced by the spatial separation these components. Geobatteries, a class redox-active substances naturally present soil-water systems, act as reservoirs, reversibly donating, storing, and accepting electrons. This capability allows temporal decoupling half-reactions, providing flexible transfer mechanism. In this review, we systematically examine critical role geobatteries influencing utilization environmental biogeochemical processes. Typical centers within geobatteries, such quinone-like moieties, nitrogen- sulfur-containing groups, variable-valent metals, possess potential repeatedly charge discharge. Various characterization techniques, ranging qualitative methods like elemental analysis, imaging, spectroscopy, quantitative techniques chemical, spectroscopic, electrochemical methods, have been developed evaluate reversible capacity. Additionally, current research on ecological significance extends beyond natural systems (e.g., soil carbon cycle) engineered water treatment nitrogen removal) waste management anaerobic digestion). Despite advancements, challenges complexity difficulties accurately quantifying exchange capacity, scaling-up issues must be addressed fully unlock their potential. review underscores both promise associated with responding issues, climate change pollutant transformation.

Low-molecular-weight organic acids inhibit the methane-dependent arsenate reduction process in paddy soils

Ecotoxicology and Environmental Safety, Год журнала: 2024, Номер 282, С. 116716 - 116716

Опубликована: Июль 16, 2024

Anaerobic methane oxidation (AOM) can drive soil arsenate reduction, a process known as methane-dependent reduction (M-AsR), which is critical driver of arsenic (As) release in soil. Low molecular weight organic acids (LMWOAs), an important component rice root exudates, have unclear influence and mechanism on the M-AsR process. To narrow this knowledge gap, three typical LMWOAs-citric acid, oxalic acetic acid-were selected added to As-contaminated paddy soils, followed by injection
