Mercury Release from Cinnabar in Water and Aqueous Solutions of Hydroquinone or Ascorbic Acid
Redox-sensitive moieties in dissolved natural organic matter have been postulated to have a mechanistic role in the dissolution of the mercuric sulfide mineral cinnabar, a reaction that may increase the bioavailability of ...
Effect of Cinnabar Age on Release of Aqueous and Volatile Mercury
Mercury release from cinnabar (α-HgS) in aqueous solutions was evaluated as a function of the age of cinnabar after pretreatment. Seventy-three batch experiments were conducted with powdered cinnabar aged from <2 h up to ...
Sulfur Speciation Analyses of Heated Soils using X-ray Absorption Near Edge Structure Spectroscopy
The determination of sulfur speciation changes in soils that result from wildfires is important for understanding the mobility of soil mercury (Hg), which is most strongly bound to reduced sulfur ligands. The transport of ...
