Sulfur dioxide is widely used in many industrial areas, for example in the production of sulfuric acid, and also as a reducing, bleaching, refrigerating agent and antioxidant. Due to a broad range of applications, it is one of the major atmospheric pollutants. Sulfur dioxide is a colorless gas with a strong odor. It is toxic, and its inhalation in high concentrations causes asphyxia, vomiting, and pulmonary edema. This book presents research data from across the globe in the study of sulfur dioxide. Some topics in this compilation include a discussion of the receptor sites for sulfur dioxide; catalysts for the SO3 decomposition reaction; the physical properties of sulfur dioxide; the theoretical insights into the photoelectron spectroscopy of sulfur dioxide and sulfur dioxide emissions control.
