Sulfetos: por que nem todos são insolúveis?
(2010)
The solubility of sulfides is discussed in this article based on the factors that can influence this property, such as predominant type of chemical bonds and structures formed in many compounds. For soluble sulfides, ...
Reactivity of inorganic sulfide species toward a heme protein model
(American Chemical Society, 2015-01)
The reactivity of inorganic sulfide species toward heme peptides was explored under biorelevant conditions in order to unravel the molecular details of the reactivity of the endogenous hydrogen sulfide toward heme proteins. ...
Characterization and kinetics of sulfide-oxidizing autotrophic denitrification in batch reactors containing suspended and immobilized cells
(IWA PUBLISHING, 2011)
Sulfide-oxidizing autotrophic denitrification is an advantageous alternative over heterotrophic denitrification, and may have potential for nitrogen removal of low-strength wastewaters, such as anaerobically pre-treated ...
Sulfide binding properties of truncated hemoglobins
(American Chemical Society, 2010-03)
The truncated hemoglobins from Bacillus subtilis (Bs-trHb) and Thermobifida fusca (Tf-trHb) have been shown to form high-affinity complexes with hydrogen sulfide in their ferric state. The recombinant proteins, as extracted, ...
Geoelectrical prospection of disseminated sulfide mineral occurrences in Camaquã Sedimentary Basin, Rio Grande do Sul State, Brazil
(2012-12-01)
The mineral exploration is a complex activity that should involve a combination of direct and indirect techniques of geological investigation. The growing demand for base metals in the national and international market ...

Fluid Inclusion and stable isotope studies at Don Sixto, a precious metal low sulfidation deposit in Mendoza province, Argentina
(Wiley, 2013-09)
The Don Sixto mining area in Mendoza province, central-western Argentina, contains an epithermal low sulfidation Au–Ag deposit. It is a small deposit (∼4 km2), with a gold resource of 36 t. In Don Sixto, ore minerals are ...
Corrosion behavior of api 5l x70 carbon steels in hydrogen sulfide environments
(2021-01-01)
As we all know, corrosion of pipelines by hydrogen sulfide is the most worrying factor in the production and transport of oil and gas. In this work the corrosion behavior of API 5L X70MS and X70MO low carbon steels in ...
Geoelectrical prospecting for a copper-sulfide mineralization in the Camaqua sedimentary basin, Southern Brazil
(Inst Geophysics Unam, 2016-07-01)
In this paper are presented the results of the combination between a resistivity method and geological surface mapping, applied to the study of an area with potential mineralization of copper sulfides sited on the northern ...
