The characteristics on the performance of a polymer electrolyte fuel cell over a change with the passage of time were clarified when the sulfur dioxide in the air was introduced into the cathode. Specifically, the influence on a cell performance was considered in case the sulfur dioxide ...
The determination of sulfur dioxide in air is based on a preliminary purification with a cellulose filter and 80% isopropanol and absorption of sulfur dioxide by means of two midget impingers in 0.3 N hydrogen peroxide. The formed sulfate is titrated in an aliquot with 0.005 M barium ...
The meaning of SULFUR DIOXIDE is a heavy pungent toxic gas SO2 that is easily condensed to a colorless liquid, is used especially in making sulfuric acid, in bleaching, as a preservative, and as a refrigerant, and is a major air pollutant especially in i
(A) The urban school was located in a part of the city in which levels of sulfur dioxide in the air were usually far lower than is typical for urban areas. (B) At both schools, the plants in the greenhouses grew much more quickly than did plants planted outdoors in plots near the g...

Apparatus and method for the efficient and economic removal of sulfur dioxide from gases, in which the gas is contacted with neutralizing values obtained from presure hydrated lime or pressure hydrated dolomitic lime, i.e. calcined limestone or dolomite and slaked with water under elevated temperature...
was connected with combustion,which was mainly produced by the combustion of coal.Sulfur dioxide can turn into acid rain in some case,which was severely damage to the human ecology.For this situation,several important purification technologies of sulfur dioxide in flue gas desulfurization were ...
