Birnessite, a layered manganese (Mn) oxide, possesses extraordinary metal adsorption and
oxidation activity, and thus imposes impacts on many biogeochemical processes. The …

Pollution of arsenic (As) in acid mine drainage (AMD) is a universal environmental problem.
The weathering of pyrite (FeS 2) and other sulfide minerals leads to the generation of AMD …

Arsenic (As) cycling in groundwater is commonly coupled to the biogeochemical cycling of
iron (Fe) and the associated transformation of Fe minerals present. Numerous laboratory …

Arsenic (As) contamination in soil and water poses a serious threat to the ecosystem health
and human beings, and is of widespread concern. The main As species found in soil and …

Oxidation and adsorption processes critically affect the mobility of antimony (Sb) in the
environment. Minerals such as manganese oxides appear to be important adsorbents or …

Elevated solution concentrations of As in anoxic natural systems are usually accompanied
by microbially mediated As (V), Mn (III/IV), and Fe (III) reduction. The microbially mediated …

Iron and manganese oxides are commonly found in nature, such as hematite and pyrolusite,
which strongly affect the migration and transformation of As (III). In this study, a series of …

Antimony (Sb) is a recognized priority pollutant with toxicity that is influenced by its migration
and transformation processes. Oxidation of Fe (II) to Fe (III) oxides, which is a common …

Gemini surfactant, 1, 1′-(butane-1, 4-diyl)-bis (3-(tetradecyloxycarbonyl) pyridinium)
dibromide (designated as NG), and the corresponding monomer, 1-ethyl-3 …

Dissimilatory iron-reducing bacteria (DIRB) affect the geochemical cycling of redox-sensitive
pollutants in anaerobic environments by controlling the transformation of Fe morphology …
