Fate and risk of metal sulfide nanoparticles in the environment. A geochemical and mineralogical study of hydrothermal deposits from 13°N and 21°N, East Pacific Rise was conducted in order to identify controls on the distribution of silver.

At 300°C, both Ag(HS)(OH)- and Ag(HS)(H2O)0 are dominant in the neutral pH range, and Ag(H2S)(H2O)2+ only exists in acidic solutions. Re-evaluation of stability and toxicity of silver sulfide nanoparticle in environmental water: Oxidative dissolution by manganese oxide. For their solvation structures, the H2S ligands donate weak H-bonds to water O; the HS- ligands accept weak H-bonds from water H; the dangling S2- form strong H-bonds with H of water molecules and the OH- ligands can form strong H-bonds as donors and weak H-bonds as acceptors.

For permission to reproduce, republish and The available experimental data on the stability constants of chloride, hydrosulfide, and hydroxo complexes of Ag(l), Cu(l), and Au(l) under hydrothermal conditions were processed. The natural organic matter (NOM) and dissolved oxygen (DO) posed effects on the Ag2SNPs dissolution by chlorine; NOM accelerated Ag2SNPs dissolution while DO reduced the rate and extent of Ag2SNPs dissolution. Question =  Is TeCl4 polar or  nonpolar   ? Little is known about the stability of Ag2SNPs in surface water disinfected with aqueous chlorine, one of the globally most used disinfectants. In these solutions, ZnS is precipitated in response to changes of temperature, pH, and S. Among them, decrease of S is more effective than that of temperature and pH. S formation: changes in deposition of silver nanoparticles with sulfidation. In order to assess the role of zinc sulfide complexes in ore-forming solutions, the solubility of sphalerite was measured in NaOH---H 2 S aqueous solutions of 0.0 to 3.0 m NaHS concentration at temperatures of 25 to 240°C. Solubilities vary with temperature, activities of H 2 S(aq) and HS - , total reduced sulfur concentration ( S), and pH. However, they become predominant zinc species in certain geothermal solutions and ore-forming solutions responsible for some epithermal precious metal deposits. le transport d’Ag notamment sous forme de complexe chloruré, et son dépôt provoqué par une diminution 2 29 publications.
