| Abstract: | A method for the determination of sulfur dioxide and sulfur trioxide in stack gases is reported in this paper and optimum conditions have been discussed thoroughly. Sulfur dioxide is absorbed quantitatively in a solution of 3% hydrogen peroxide and sulfur trioxide absorbed guantitatively in 80% isopropyl alcohol solution,which inhibits oxidation of sulfur dioxide. Then the sulfate was titrated with standard barium chloride solution in 80% isopropyl alcohol using Thorin as indicator. The proposed method is simple and the titration is rapid. It is convenient to determine and control sulfur dioxide and sulfur trioxide insite. |
