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...
Removal of arsenate and arsenite from aqueous solution by adsorption on clay minerals
Sorption of arsenic species [As(V) and As(III)] on different clay minerals including kaolinite (KGa-1), montmorillonite (SWy-1), and nontronites (NAU-1 and NAU-2) with respect to sorption kinetics, isotherms and pH was investigated. As(V) and As...
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...
