RISRemoval of chromium [Cr(VI)] from contaminated solutions by using biogenic ferrous iron in bioreduced minerals
Abiotic reduction of Cr(VI) by ferrous iron was investigated in the presence of bioreduced goethite, hematite and two types of nontronites (NAU-1 and NAU-2). Bioreduction experiments were performed with structural Fe(III) in the minerals as sole...
Influence of clay minerals on sorption and bioreduction of arsenic under anoxic conditions
Adsorption of As(V) on various clay minerals including kaolinite (KGa-1), montmorillonite (SWy-1) and nontronites (NAU-1 and NAU-2), and subsequent bioreduction of sorbed As(V) to As(III) by
bacterium Shewanella putrefaciens strain CN-32 were...
Impact of Bioreduction on Remobilization of Adsorbed Cadmium on Iron Minerals in Anoxic Condition
The impact of bioreduction on the remobilization of adsorbed cadmium Cd(II) on minerals, including hematite, goethite, and two iron(III)-rich clay minerals nontronites (NAU-1 and NAU-2) under anoxic conditions was investigated. Langmuir isotherm...
Isolation and Identification of Ferric Reducing Bacteria and Evaluation of their Roles in Iron Availability in Two Calcareous Soils
Iron is an essential element for all organisms which plays a crucial role in important biochemical
processes such as respiration and photosynthesis. Iron deficiency seems to be an important problem in many calcareous ...
