Birnessite not only oxidizes arsenite into arsenate but also interacts with organic matter in
various ways. However, effects of organic matter on interaction between As and birnessite …

Manganese oxides and organic acids are key factors affecting arsenic mobility, but As (III)
oxidation and adsorption in the coexistence of birnessite and low molecular weight organic …

In an aquatic ecosystem, especially constructed wetlands receiving arsenic (As)-containing
wastewater, the fate and mobility of As is influenced by manganese (Mn) oxides and organic …

Arsenite is more toxic and mobile than As (V) in soil and sediment environments, and thus it
is advantageous to explore factors that enhance oxidation of As (III) to As (V). Previous …

Arsenite (As (III)) is a more toxic form of inorganic arsenic and its removal from drinking
water is less effective compared with arsenate (As (V)). In the present study, synthetic …

Oxidation of As (III) by three types of manganese oxides and the effects of pH, ion strength
and tartaric acid on the oxidation were investigated by means of chemical analysis …

Reductive release of the potentially toxic metalloid As from Fe (III)(oxyhydr) oxides has been
identified as an important process leading to elevated As porewater concentrations in soils …

Manganese (IV) oxides, and more especially birnessite, rank among the most efficient metal
oxides for As (III) oxidation and subsequent sorption, and thus for arsenic immobilization …

Manganese (III/IV) oxides are naturally occurring oxidants of arsenic (As) and can transform
the more mobile and toxic arsenite [As (III)] to the less mobile and less toxic arsenate [As …

Manganese (Mn) and iron (Fe) oxides are ubiquitous solids in terrestrial systems that have
high sorptive capacities for many trace metals, including arsenic (As). Although numerous …
