Direct Sulfation of Limestone by Sulfur Dioxide

Study and Kinetic Modeling of Direct Sulfation of Iranian Limestones by Sulfur Dioxide at High CO2 Partial Pressure

The direct sulfation of three high purity Iranian limestones and one precipitated calcium carbonate from different sources, containing more than 97 % CaCO3, were studied in a specially designed fixed bed reactor under atmospheric pressure, in the presence of excess CO2 to prevent decomposition of CaCO3. Experiments were carried out over a range of particle s...

Sulfur 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...
