A heterogeneous nanoadsorbent composed of two-dimensional Ti3C2Tx MXene nanosheets (MX) functionalized with nanolayered molybdenum disulfide (MoS2/MX-II) was synthesized by a facile hydrothermal treatment method and used to remove toxic mercuric ions (Hg2+). Mercury was adsorbed by the synergistic action of the sulfur (disulfide) and the oxygenated...

In this article, a magnetic cobalt-iron modified porous carbon derived from agricultural wastes by microwave and steam activation was developed to remove elemental mercury in coal-fired flue gas. The effects of operating parameters on Hg0 capture were discussed. Reaction mechanism and regeneration performance were also studied. Results show that th...

Mercury contamination in soil, water and air is associated with potential toxicity to humans and ecosystems. Industrial activities such as coal combustion have led to increased mercury (Hg) concentrations in different environmental media. This review critically evaluates recent developments in technological approaches for the remediation of Hg cont...

The kinetics of elemental mercury (Hg0) release from fly ashes and hydrated fly ash cement pastes was investigated using a homemade Hg measurement system. Three types of fly ash (FA) and ordinary Portland cement (OPC) were used to prepare cement pastes. After standard curing for 28 days, the hydrated cement paste (HCP) was ground into a fine powder...

In this study, TiO2 nanotubes (TNTs) and AgCl-modified TNTs nanocomposites with multiple crystal phases were synthesized through a hydrothermal method without calcination. The resultant samples had a large Brunauer-Emmett-Teller surface area. Additionally, the Ag modification process reduced the recombination rate of electron-hole pairs in the synt...

A series of Mn–Ni/AC (AC, activated coke) catalysts were synthesized by the impregnation method for the removal of elemental mercury (Hg0) from simulated flue gas. The samples were characterized by BET, ICP-OES, SEM, XRD, XPS, H2-TPR, FT-IR, and TGA. Mn6Ni0.75/AC exhibited optimal removal efficiency of 96.6% in the condition of 6% O2 and balanced i...

Mercury (Hg) is a potentially harmful trace element in the environment and one of the World Health Organization's foremost chemicals of concern. The threat posed by Hg contaminated soils to humans is pervasive, with an estimated 86 Gg of anthropogenic Hg pollution accumulated in surface soils worldwide. This review critically examines both recent a...

Graphitic carbon nitride (g-C3N4) with unique and versatile properties has gained increasing research concerns. Here, CuO/g-C3N4 nanocomposite is fabricated and employed for gas-phase mercury (Hg0) removal at low temperature. Pure g-C3N4 performs well toward Hg0 adsorption at 40–200 °C with the optimal Hg0 removal efficiency of ~ 54.5% at 120 °C. C...

Industrial use has led to the presence of liquid elemental mercury (Hg0) worldwide in the subsurface as Dense NonAqueous Phase Liquid (DNAPL), resulting in long lasting sources of contamination, which cause harmful effects on human health and detrimental consequences on ecosystems. However, to date, insight into the infiltration behaviour of elemen...

Millimeter resin-based activated carbon spheres were introduced for the removal of elemental mercury, and some metallic oxides were doped to activated carbon spheres to enhance the Hg0 removal ability. The experimental results indicated that prepared activated carbon spheres (PAC) and PAC-Cu presented almost identical with a smooth surface without ...
