Fungal formation of selenium and tellurium nanoparticles

 · Selenium and tellurium are metalloids with chemical properties similar to sulfur, also belonging to Group 16 of the Periodic table, ... Remaining substrates from copper mining and refining may contain selenium at various concentrations ranging from 10–40%. Tellurium concentrations are usually much lower, being around 5% maximum (George 2004). Only 15% of the 2700 tonnes of .

Tellurium, selenium and cobalt enrichment in ...

Tellurium is fractionated from its common partner Se in oxidising conditions by adsorption on iron oxide, while Se is soluble in oxidising conditions (Kashiwabara et al., 2014) and not enriched in ferromanganese crusts. The expense and environmental impact of seafloor mining are key issues in the extraction of ferromanganese crusts, which may become utilised as demand for Co and Te increases.

DETERMINATION OF SELENIUM AND TELLURIUM OXYANION .

selenium and tellurium oxyanions to the test organism. Bacteria were grown in Petri dishes with a paper disk placed in its center which was saturated with a metalloid solution of various concentrations. A zone of growth inhibition observed around this disk was used as a measure of relative toxicity of these oxyanions. The second set of experiments carried out included the identifiion of ...

Recovery of tellurium from high telluriumbearing ...

 · Tellurium and selenium can be first dissolved into the alkaline solution through pressure leaching, separated from the insoluble components. And then the alkaline leaching solution is neutralized to precipitate the crude TeO 2, which can be purified in the existing process. The purpose of this study is to conduct a thermodynamic analysis of alkaline leaching process, and to selective extract ...

Tellurium Distribution and Speciation in Contaminated ...

The distribution and chemical species of tellurium (Te) in contaminated soil were determined by a combination of microfocused Xray fluorescence (μXRF), Xray diffraction (μXRD), and Xray absorption fine structure (μXAFS) techniques. Results showed that Te was present as a mixture of Te(VI) and Te(IV) species, while selenium (Se) was predominantly present in the form of Se(IV) in the ...
