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 …

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 …

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

We used a combination of batch studies and spectroscopic analyses to assess the impacts
of aqueous Mn (II) on the solubility and speciation of Zn (II) in anoxic suspensions of …

We investigated the effect of pH (5.5–8.5) on the mineralogical transformation of hexagonal
birnessite induced by reaction with aqueous Mn (II)(50–2200 μM), using batch sorption …

Mn oxides (MnOx) are ubiquitous metal oxide minerals in nearly all environmental settings.
They play important roles in the transport and fate of many environmental components such …

Environmental context The release of antimony and its compounds to the environment can
present a toxic hazard for humans. We evaluated the use of birnessite to dissolve antimony …

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 ubiquitous in the natural environment where heavy metals are retained and
easily transformed. The surface properties and structure of birnessite change with the …

The structure and Mn (III) concentration of birnessite dictate its reactivity and can be
changed by birnessite partial reduction, but effects of pH and reductant/birnessite ratios on …
