Reduction of Hg(II) to Hg(0) by Magnetite

Environmental Science & Technology, 2009
Mercury (Hg) is a highly toxic element, and its contamination of groundwater presents a significant threat to terrestrial ecosystems. Understanding the geochemical processes that mediate mercury transformations in the subsurface is necessary to predict its fate and transport. In this study, we investigated the redox transformation of mercuric Hg (Hg[II]

Spurenbestimmung von Hg(I)/Hg(II) oder Hg(0)/Hg(I) nebeneinander sowie indirekte Bestimmung von Hg-komplexierenden Anionen mit dem Kaltdampf-AAS-Verfahren

Fresenius' Zeitschrift für analytische Chemie, 1985
Die Anwendung des Kaltdampf-Verfahrens fur die Speziesanalyse des Quecksilbers wurde untersucht. Wechselwirkungen von Hg(II) mit Hg(0) zu Hg(I) und mit komplexierenden Anionen machen folgende Bestimmungen moglich: Hg(II) und Hg(I) nebeneinander, Hg(0)-Gehalt der Luft sowie neben Hg(I) und Quecksilberkomplexierende Anionen. Die Verfahren beruhen darauf,

Thermodynamic assessment of binary Zn-Hg, Cd-Hg, AND In-Hg amalgams

Calphad, 1998
Abstract A thermodynamic assessment of the binary Zn-Hg, Cd-Hg and In-Hg systems has been completed. A set of parameters describing the Gibbs energy of each phase is given. Comparison between calculated quantities and experimental data is generally good.

Hg–Hg bonding and its influence on the stability of (HgS)_n clusters

Physical Chemistry Chemical Physics
Pulsed laser ablation of HgS(s) shows the formation of (HgS)n=2–4+, HgSn=1–8±, and HgmSn± cluster ions. Theoretical analysis evidences that Hg–Hg interaction plays a vital role in the stability of (HgS)n and validates experimental observation.
