Abstract |
Two prototype automatic atmospheric pollutant analyzers suitable for producing dosimeter or continuously integrated records have been designed and constructed. The Zirconium-Eriochrome Cyanine R reagent for fluoride and the Starch-Iodine Blue reagent for sulfur dioxide have been moditied for use in the analyzers. The reduced stability of these reagents under continuous air aeration for periods exceeding 4-12 hours limits the pollutant concentration which may be accumulated by a single reagent charge. This appears, however, to be desirable from the viewpoint of field application. Simultaneous comparisons were made between the Thomas Autometer, Titrilog and the Dosimeter for sulfur dioxide and an automatic scrubbing soulution collector and the Dosimeter for hydrogen fluoride. |
