This paper presents the synthesis, structural characterization and Pb (II) adsorption behavior
of K-birnessite and H-birnessite samples. Changes in the surfaces and structure of …

The aim of this study was to examine the adsorption characteristics of cationic surfactant
modified-birnessite for removal of Pb. For this purpose, Na-birnessite and …

Removal of cadmium, copper and lead with microporous synthetic Na-birnessite (sodium-
birnessite) was investigated by carrying out batch-type sorption experiments with 2 days of …

This paper presents the adsorption of Pb (II) from aqueous solution by raw sepiolite (RS)
and iron oxide-coated sepiolite (ICS) samples. Adsorption of Pb (II) by RS and ICS sample …

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 …

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 …

Nano-birnessite was prepared, characterized and used for removal of cobalt and strontium
ions from aqueous solutions. Scanning electron microscope and atomic force microscope …

Sorption is an efficient process for transferring heavy metals from polluted water to solid
phase. Birnessite, which is a non-toxic layered manganese oxide, is particularly interesting …

Behavior of adsorption, desorption and oxidation of Cr (III) on birnessite was studied in this
paper. The results showed that the total adsorption amount of Cr (III) increased with …

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 …
