Elemental mercury (Hg(0)) in flue gases can be efficiently captured by mercury chloride (HgCl2) solution. However, the absorption behaviors and the influencing effects are still poorly understood. The mechanism of Hg(0) absorption by HgCl2 and the factors that control the removal were studied in this paper. It was found that when the mole ratio of Cl(-) to HgCl2 is 10:1, the Hg(0) removal effic...

Removal rate and durability are the two most important parameters of an ideal air purification filter to remove inhalable particles toxic gases. Here, based on interaction a local electric field external field, novel coaxial core–shell CuO@NH2-MIL-53(Al) nanowire array was synthesized rigid copper net, which used PM2.5 SO2 simultaneously. The removal rates by with without can reach 98.72% 44.41...

Stratospheric aerosols (SAs) are a variable component of the Earth's albedo that may be intentionally enhanced in the future to offset greenhouse gases (geoengineering). The role of tropospheric-sourced sulfur dioxide (SO2) in maintaining background SAs has been debated for decades without in-situ measurements of SO2 at the tropical tropopause to inform this issue. Here we clarify the role of S...

Aiming at NOx (NO 90%, NO2 10%) and SO2 in simulated vessel emissions, denitration desulfurization were studied through ozone oxidation combined with seawater as absorbent. Specifically, the different influencing factors of analyzed. The results indicated that efficiency NO can reach over 90% when molar ratio O3/NO is 1.2. Ozone washing same unit decrease temperature NO, avoid high decompositio...

Sulfur dioxide (SO2) is a gaseous environmental pollutant which is routinely used in industry as a preservative and antimicrobial. Recent data suggests that SO2 may have value as a therapeutic agent. However, due to its gaseous nature, localizing SO2 generation is challenging. Herein, various 1,3-dihydrobenzo[c]thiophene 2,2-dioxides (benzosulfones) were prepared as candidates for photochemical...

Membrane Condenser (MC) is a novel membrane contactor operation recently investigated for the valorization of industrial waste gaseous streams. In particular, until now, it was applied for water recovery from flue gas, cooling tower plumes, etc. More recently, its effectiveness and flexibility in contaminants (such as, NH3 , HF, SO2 ) removal and control from waste gaseous streams was also prov...

Abstract. A novel technique has been developed to measure sulfur dioxide (SO2) using a modification of the existing electrochemical concentration cell (ECC) ozonesonde technology. The current sonde-based method SO2 (i.e., dual-sonde approach) involves launching two ozonesondes together, with one sondes having filter remove at inlet. profile is determined by taking difference between measurement...

The V2O5-modified palygorskite (V2O5/PG catalysts) were prepared and used for Hg0 removal in simulated flue gas at low temperature. It was found that the V2O5/PG catalyst had excellent performance 150 °C. O2 exhibited a positive effect on over V2O5/PG, while SO2 H2O showed an inhibiting effect. However, efficiency promotion trend presence of H2O, SO2, O2. Brunauer–Emmett–Teller (BET) method, sc...
