Sulfur Isotopic Fractionation in Vuv Photodissociation of Sulfur Dioxide: Implications for Meteorite Data
Introduction: Mass independent sulfur isotopic compositions have been observed in chondritic chondrules and organics [1, 2] and in bulk CM chondrites, achondrites and iron meteorites [3-6]. A significant excess of ∆33S (= δ33S – 0.515 δ34S) was observed in the Dhajala chondrite. Sulfonic acid extracts from the carbonaceous chondrite, Murchison also displayed a significant 33S anomaly and may be...
متن کاملMass-independent sulfur isotope fractionation during photochemistry of sulfur dioxide
Mass-independent sulfur isotope signatures are observed in Archean and early Paleoproterozoic sedimentary sulfate and sulfide minerals, and provide the most robust constraints on early atmospheric oxygen levels. Smaller mass-independent sulfur isotope anomalies are observed in ice cores and interpreted as a tracer of stratospheric volcanic loading. Photochemistry of sulfur dioxide (SO 2) has be...
متن کاملSulfur dioxide emissions in Iran and environmental impacts of sulfur recovery plant in Tabriz Oil Refinery
Background: Combustion of fossil fuels contributes to sulfur dioxide (SO2) emissions. To deal with this issue, the government of Iran has appointed the oil refineries to upgrade their installations and produce high quality fuels. Thus, this study investigated the status of SO2 emissions in Iran and the capability of advanced technologies to control SO2 emissions. Methods: The status of SO2 em...
متن کاملSulfur Dioxide
The ubiquity of sulfur dioxide as an air pollutant combined with reports of effects of the gas and its blood metabolite on DNA and chromosomes, prompted a study of possible mutagen action on mammalian oocytes. Utilizing in vitro and in vivo systems, mouse, ewe, and cow oocytes were examined for cytologic evidence of structural or numerical damage in meiosis. Fragmentation with rearrangement see...
متن کاملSulfur Dioxide Crossover during the Production of Hydrogen and Sulfuric Acid in a PEM Electrolyzer
A proton exchange membrane PEM electrolyzer has been investigated as a viable system for the electrolysis step in the thermochemical conversion of sulfur dioxide to sulfuric acid for the large-scale production of hydrogen. Unfortunately, during operation, sulfur dioxide can diffuse from the anode to the cathode. This has several negative effects, including reduction to sulfur that could potenti...
