Book Description
The determination of hydrogen sulfide in effluents from coal-fired furnaces and incinerators is complicated by the presence of sulfur oxides (which form acids). Organic compounds also may interfere with or prevent the formation of the cadmium sulfide precipitate or give false positive results because of reaction with iodine. The report presents a technique in which these effects are overcome by collecting the gases in a strongly basic medium and separating the cadmium sulfide by filtration. Subsequent analysis is preformed by visual comparison or iodometrically depending on the quantity of cadmium sulfide present. (Author).

Book Description
An analytical technique is described for determining the SO2 concentration in flue gases. In the method, SO2 is absorbed by a 3% hydrogen peroxide solution, the particulates filtered, and the solution titrated with barium chloride to precipitate barium sulfate.
