Triclinic birnessite (TB), a typical layered Mn oxide which is abundant naturally occurring
minerals with a vital impact on the transformation of arsenite (As (III)) by adsorption and …

Birnessites are abundant naturally occurring minerals with high sorption and oxidation
capacity that could therefore play an important role in antimony (Sb) migration and …

In the environment, antimony as a priority control pollutant is mainly associated with Fe-or
Mn-related minerals. In this work, acid birnessite (AB) doped with iron was synthesized as …

Birnessite is regarded as an efficient oxidizing agent that would significantly influence the
environmental fate of elements such as arsenic. This study compared the chemical and …

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 (Mn) oxides, such as birnessite (δ-MnO2), are ubiquitous mineral phases in
soils and sediments that can interact strongly with antimony (Sb). The reaction between …

Co-containing birnessites were obtained by ion exchange at different initial concentrations
of Co2+. Ion exchange of Co2+ had little effect on birnessite crystal structure and …

Birnessite, a phyllomanganate and the most common type of Mn oxide, affects the fate and
transport of numerous contaminants and nutrients in nature. Birnessite exhibits hexagonal …

Manganese (Mn) oxide minerals, such as birnessite, are thought to play an important role in
affecting the mobility and fate of antimony (Sb) in the environment. In this study, we …

Hexagonal birnessite is the most ubiquitous manganese oxide in geological environments. It
is often highly enriched in trace metal ions such as Ni and plays an important role in metal …
