Abstract
Provided is an oxidation method and oxygen apparatus of sulfur compounds in a gas in which stable sulfur compounds such as carbonyl sulfide can be easily converted into sulfur oxide, and an analysis apparatus of sulfur compounds to which the oxidation method and the oxidation apparatus are applied. Sulfur compounds other than sulfur dioxide contained in a gas is subjected to a silent discharge treatment, whereby those sulfur compounds are oxidized and converted into sulfur dioxide. The analysis apparatus includes a silent discharge treatment unit in which a gas containing sulfur compounds is subjected to a silent discharge treatment to oxidize sulfur compounds other than sulfur dioxide to be converted into sulfur dioxide, and an analyzing unit in which the concentration of sulfur dioxide contained in the gas which has been subjected to silent discharge treatment in the silent discharge treatment unit is measured.
