摘要:... In many biological treatment processes, nitrate as a thermodynamically more preferable electron acceptor inhibits selenate reduction. Here we report on an enrichment of a bacterial assemblage from a mine impacted natural marsh sediment that was capable of simultaneous selenate...

摘要:... In this work, X-ray photoelectron spectroscopy was applied to reveal a difference in selenate removal speciation-level pathways (with a focus on solid phase) altered by its major competitor, sulfate. It was defined that sulfate greatly influenced the mechanism of selenate...

摘要:Abstract(#br)Methane oxidation coupled to selenate reduction has been suggested as a promising technology to bio-remediate selenium contaminated environments. However, the effect of dissolved oxygen (DO) on this process remained unclear. Here, we investigate the feasibility of selenate...

摘要:... Sulphur starvation had a positive effect on selenate uptake and the form of Se supplied greatly influenced Se speciation in plants. Compared with the control plants, Se uptake by the S-starved plants was enhanced by 4.81-fold in the selenate treatment, and selenate was readil...

摘要:Abstract(#br)Iron-impregnated granular activated carbon (Fe-GAC) has been shown effective for selenite adsorptive removal from aqueous solutions, but similar effectiveness was not observed with selenate. This study examined the effects of background electrolytes and pH on selenate...

摘要:... For the Fe series, all attempts to dehydrate the samples doped with selenate resulted in amorphous products, and it is suspected that a side redox reaction involving the Fe and selenate may be occurring leading to phase decomposition and hence the lack of a crystalline produ...

摘要:Abstract(#br)The selenate removal mechanism of hydrogen-based membrane biofilm reactor (MBfR) for nitrate-polluted groundwater treatment was studied based on anaerobic biofilm analysis. A laboratory-scale MBfR was operated for over 60 days with electron balance, structural a...

摘要:... CKCr-6A that was isolated from Sabzevar of Iran catalyzes the NADH-dependent reduction of selenate and selenite to elemental selenium. Selenate reductase enzyme was purified with following purification process involved (NH 4 ) 2 SO 4 precipitation, followed by using Q-Seph...

摘要:Abstract(#br)This paper describes the activity of Pt catalysts supported on metal-oxides (TiO 2 , ZrO 2 and Al 2 O 3 ) for the reduction reaction of selenate with hydrazine monohydrate in aqueous solution. The Pt/TiO 2 catalyst exhibited superior performance in the reduction reac...

摘要:Abstract(#br)Microorganisms can remove selenate (SeO 4 2− ) in water by converting it to elemental selenium nanoparticles. Conventional biological reactors usually simultaneously produce intracellular and extracellular elemental selenium nanoparticles or only produce intracell...
