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 …

Nanostructured Co-doped birnessites were successfully synthesized, and their application
for the removal of Pb2+ and As (III) from aquatic systems was investigated. Powder X-ray …

The relationship between vacant Mn structural sites in birnessites and heavy-metal
adsorption is a current and important research topic. In this study, two series of birnessites …

Adsorption of Cs+ on biogenic birnessite was investigated and compared with (ad) sorption
of other heavy metals and also with (ad) sorption on chemically synthesized birnessite. The …

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 …

Purpose Lead contamination is ubiquitous, and much attention has been paid due to its
toxicity. The phyllomanganate birnessite is the most common Mn oxide in soils. The MnO 6 …

Remediating aqueous solution contaminated by cobalt and strontium using synthetic
Birnessite was investigated. Birnessite structure and chemical properties were evaluated; …

Although the adsorption of cesium (Cs) onto phyllosilicate minerals has been widely studied,
the effect of Cs on redox-sensitive biogenic Mn oxide is not well understood. In this study …

Na-rich birnessite (NRB) was synthesized by a simple synthesis method and used as a high-
efficiency adsorbent for the removal of ammonium ion (NH 4+) from aqueous solution. In …

The amount of Mn2+ adsorbed or removed from solution by birnessite is several times
greater than its reported cation exchange capacity. Extractability of the sorbed Mn2+ …
