Sulphur Chemistry in KOH-SO2 Activation of Fluid Coke and Mercury Adsorption from Aqueous Solutions
… from KOH-SO2 activation showed a comparable Hg2+ adsorption capacity (43 – 72 mg/g) with those reported in the literature (35-100 mg/g) and that of a commercial SIAC (41 mg/g). Although a larger SBET often resulted in a greater Hg2+ adsorption capacity, the benefit started to diminish when SBET …

Preparation and Evaluation of Sulfur -Containing Adsorbents for Removal of Mercury From Simulated Coal Combustion Flue Gases
… the adsorbents' Hg0 and HgCl2 equilibrium adsorption capacities. Results indicate that low-cost, high-capacity adsorbents (e.g., CDACs) can be developed from precursors containing inherent sulfur (e.g., coal). The resulting samples, without using sulfur impregnation, achieved mercury …

Design of chemically treated activated carbon fibers for mercury removal and advanced membranes for water purification
… chemically treated activated carbon fibers for mercury removal from power plant effluents, and the other one is to design advanced nanofiltration membranes for water purification with specific features, i.e. solvent resistance and antifouling properties. The current technologies for mercury …

Evaluation of sorbents for the cleanup of coal-derived synthesis gas at elevated temperatures
… but also sulfur and trace metals such as lead or mercury. One potential method to improve the efficiency for IGCC is through the use of solid sorbents that operate at elevated temperatures. Because many of these technologies are in their infancy and have yet to be commercially demonstrated, a …

Photochemical transformation of particulate organic carbon and its impact on mercury cycling in aqueous systems
Mercury (Hg) is a global pollutant with high toxicity that accumulates in biota and biomagnifies, posing a risk to organisms throughout the food chain. Mercury is known to strongly associate with natural organic matter (NOM), which, in turn, affects its speciation, solubility, mobility and …

Investigation of constructed wetlands capability to remove mercury from contaminated waters
… (c) acidic; and (d) agricultural wastewater. Mercury has been used intensively by wide variety of industries because of its unique properties. Consequently, it was present at various levels in wastewater discharged. The ability of constructed wetlands to serve as a sink of mercury before …
