Despite worldwide effort, most electric power is still generated by the combustion of fossil
fuel. Among the various combustion exhaust gases, SO 2 and NOx can exert adverse effects …

There is currently a renewed interest in develo** microalgae as a source of renewable
energy and fuel. Microalgae hold great potential as a source of biomass for the production of …

Power plants emit sulfur dioxide (SO 2) during combustion, which is typically removed via
wet flue gas desulfurization, but this process produces numerous secondary pollutants. Ionic …

Uneven distribution and excess accumulation of biomass within gas phase biofilters often
result in operational problems such as clogging, channeling, and excessive head loss within …

To explore environmentally benign solvents for absorbing SO2, a series of hydroxyl
ammonium ionic liquids (ILs) was synthesized and characterized, and the solubilities of SO2 …

The acute toxicity of engineered nanoparticles (NPs) in aquatic environments at high
concentrations has been well-established. This study demonstrates that, at a concentration …

Removal of hydrogen sulfide from waste and energy-rich gases is required, not only
because of environmental health and safety reasons, but also because of operational …

The removal of sulfur by deep hydrodesulfurization is expensive and environmentally
unfriendly. Additionally, sulfur is not separated completely from heterocyclic poly-aromatic …

Abstract Treatment of high-strength sulfate wastewaters is becoming a research issue not
only for its optimal management but also for the possibility of recovering elemental sulfur …

SO2 gas is toxic for humans, and extended exposure to low concentration SO2 gas can
trigger bronchitis and other respiratory impairments, thus leading to an increased mortality …
