Manganese (Mn) is a biologically important and redox-active metal that may exert a poorly
recognized control on carbon (C) cycling in terrestrial ecosystems. Manganese influences …

The chemistry of Fe and Mn in natural geochemical systems are closely coupled, as Fe and
Mn always co-exist in various forms (eg, hydrated ions, soluble complexes, and particles) in …

Hexavalent chromium contamination is a global environmental issue and usually reoccurs in
alkaline reduced chromite ore processing residues (rCOPR). The oxidation of Cr (III) solids …

MnO 2 with various structures, including three tunnel structures (α-, β-, γ-MnO 2) and a
layered structure (δ-MnO 2), were synthesized and investigated for peroxymonosulfate …

Manganese dioxides (MnO2) are among important environmental oxidants in contaminant
removal; however, most existing work has only focused on naturally abundant MnO2. We …

Tongling is a typical metal ore concentration area in the Yangtze Metallogenic Region.
Years of mining activities have resulted in serious regional groundwater problems …

Mn-modified biochars (BCs) were developed by pre-treatment of feedstock (MBCs) or post-
modification of biochar (BCM), for simultaneous adsorption and degradation of a model …

Sunlight drives photosynthesis and associated biological processes, and also influences
inorganic processes that shape Earth's climate and geochemistry. Bacterial solar-to …

In this study, we investigated the impact of fluctuating water levels on the distribution of lead
(Pb) and zinc (Zn) in soil and sediments at a historical Pb-Zn smelting site along the …

Abstract Chromium (VI)(Cr (VI)) is an environmental priority pollutant, and its mobility in
natural environment is strongly controlled by ferrihydrite. Ferrihydrite always contains …
