SO2-Driven In Situ Formation of Superstable Hg3Se2Cl2 for Effective Flue Gas Mercury Removal

Haomiao Xu et al.

Summary: A superstable Hg3Se2Cl2 compound is discovered and proven to be a promising solution for efficient and safe flue gas mercury removal. The compound exhibits high thermal stability and strong acid resistance, and laboratory experiments demonstrate its exceptional performance in removing mercury from flue gas. This study highlights the importance of stable demercury products in flue gas treatment and provides an efficient and practical demercury strategy.

An updated global mercury budget from a coupled atmosphere-land-ocean model: 40% more re-emissions buffer the effect of primary emission reductions

Yanxu Zhang et al.

Summary: The effectiveness of reducing environmental mercury levels by controlling anthropogenic emissions depends on the magnitude of re-emissions from the land and ocean. Recent advances in atmospheric mercury chemistry, vegetation uptake, seawater mercury sources, and riverine discharges challenge our understanding of the global mercury cycle. A new coupled atmosphere-land-ocean model suggests potentially higher atmospheric mercury emissions and emphasizes the need for more aggressive emission control to decrease mercury levels.

Latitudinal Distribution of Gaseous Elemental Mercury in Tropical Western Pacific: The Role of the Doldrums and the ITCZ

Fange Yue et al.

Summary: The role of the tropical western Pacific in shaping the latitudinal distribution of atmospheric mercury is significant. Factors such as the doldrums, Intertropical Convergence Zone (ITCZ) and wet deposition contribute to the accumulation of elemental mercury (GEM) and dissolved gaseous mercury (DGM) in this area.

The Chemistry of Mercury in the Stratosphere

Alfonso Saiz-Lopez et al.

Summary: This article presents the first model of stratospheric mercury chemistry and identifies two distinct mercury chemical regimes. The study also reveals that the oxidation of mercury in the stratosphere is faster than previously assumed, but regulated by photo-reduction. The lifetime of mercury in the stratosphere shows a significant variation.

Single-Molecule Force Spectroscopy Reveals the Dynamic HgS Coordination Site in the De Novo-Designed Metalloprotein α3DIV

Ziyi Wang et al.

Summary: The de novo-designed metalloprotein alpha 3DIV binds to mercury via three cysteine residues under dynamic conditions. An unusual trigonal three-coordinate HgS3 site is formed in the protein in basic solution, whereas a linear two-coordinate HgS2 site is formed in acidic solution. It is found that any two of the three cysteines in the protein bind to mercury in the HgS2 site.

Reduction of HgCl2 to Hg0 in flue gas at high temperature. Part II: Acid remover

Tianfang Huang et al.

Summary: Eliminating the adverse effects of oxidative species on the reduction of HgCl2(g) to Hg-0(g) is crucial for ensuring the accuracy of total gaseous mercury measurement. An efficient acid remover (AR) was developed to overcome these effects. The study found that CaO/30%gamma-Al2O3 composite material has the best performance in reducing re-oxidation and promoting reduction reactions.

Mercury atmospheric emission, deposition and isotopic fingerprinting from major coal-fired power plants in Australia: Insights from palaeo-environmental analysis from sediment cores

Larissa Schneider et al.

Summary: Research indicates that mercury deposition in lake sediments in Australia's Hunter Valley and Latrobe Valley has significantly increased since the commissioning of coal-fired power plants. The Latrobe Valley has higher mercury emissions due to higher concentrations in lignite coal, lax regulation, and older pollution-control technologies adopted by coal-fired power plants in that region. Australia faces the challenge of ratifying the Minamata Convention and developing better regulation policies to reduce mercury emissions in the future.

Regeneration Characteristics of Elemental Sulfur-Modified Activated Carbon for Mercury Removal

Cong Chen et al.

Summary: The study demonstrated that thermally renewable sulfur-loading on activated carbon modified with elemental sulfur not only achieved efficient mercury removal, but also showed excellent regeneration characteristics. Under optimal preparation conditions, the adsorbents reached a maximum Hg-0 breakthrough rate of less than 8.58% at 150 degrees Celsius.

Heterogeneous Reaction Mechanisms and Functional Materials for Elemental Mercury Removal from Industrial Flue Gas

Haomiao Xu et al.

Summary: This study discusses the principles and applications of solid materials in the treatment of gaseous mercury, including processes such as catalytic oxidation, physical adsorption, and chemical adsorption. Overcoming surface bonding energies can convert Hg-0 to Hg2+ via a catalytic process, while strong bonding energies ensure chemical adsorption and solidify mercury on the surface.
