Method for measuring gaseous sulfur dioxide |
摘要 |
An improved gaseous sulfur dioxide galvanic cell is formed by utilizing a solid electrolyte composed of a mixture of lithium sulfate and silver sulfate. A reference electrode is formed by placing a solid mixture of the electrolyte mixture and metallic silver in contact with a portion of the surface of the solid electrolyte. A gas-type detector electrode is provided by contacting the solid electrolyte with a gold lead at a point spatially separated from the contact point between the reference electrode and electrolyte. Catalyst means are preferably provided to convert the sulfur dioxide to an equilibrium mixture of sulfur dioxide and sulfur trioxide near the electrolyte detector electrode surface. The electrolyte is preferably heated to a temperature at which it is a two-phased mixture of solid solutions for increased long term stability.
