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 …

Abstract Birnessite (δ-Mn (IV) O 2) is a great manganese (Mn) adsorbent for dissolved
divalent metals. In this study, we investigated the coprecipitation mechanism of δ-MnO 2 in …

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 …

Cetyltrimethylammonium modified birnessite (CTMA-birnessite) is prepared by a simple
hydrothermal method. The synthetic birnessite materials are characterized by a number of …

We studied the impacts of aqueous Mn (II)(1 mM) on the sorption of Ni (II)(200 μM) by
hexagonal birnessite (0.1 g L− 1) at pH 6.5 and 7.5 with batch experiments and XRD, ATR …

Manganese oxides have been extensively investigated for arsenic (As) adsorption from
aqueous solution. However, the effect of electrochemical redox reactions on the adsorption …

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 …

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 …

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 …
