Investigations towards a better understanding of arsenic-sulfur speciation in aquatic environments: Formation, stability, structural characterization, and conflicting analyses
… the nature of these species, thioarsenites vs. thioarsenates, has been under intense debate. The major objective of the present PhD work was to improve the current knowledge about As-S species by structural characterization, investigations of their occurrence, formation and transformation, and …

Schwefelhaltige Arsenspezies in Grundwässern
… unter Sulfat reduzierenden Bedingungen, Thioarsenate gebildet werden. In Lehrbüchern und Fachpublikationen aus den vergangenen Jahrzehnten wurde bislang ausschließlich die Existenz von Thioarseniten vermutet. Ursache für die Bildung von Thioarsenaten ist eine hohe Affinität zwischen Arsen …

Importance of Sulfide, Polysulfides, and Elemental Sulfur for Abiotic and Biotic Redox Processes in Sulfur-Metal(loid)Systems
… sulfide and to rapidly oxidize to pentavalent thioarsenates. The latter were suggested to form directly by the reaction of arsenite with polysulfides. In the present study, polysulfides were found to react with arsenite to form monothioarsenate. Moreover, the higher nucleophilicity of …
