The concentration of inorganic fluorides in the atmosphere has become a matter of concern in certain agricultural and urban areas. Atmospheric fluorides are readily accumulated by vegetation, where they may be injurious to sensitive plants or have a deleterious effect on livestock that consume the vegetation. Obviously, reliable methods of determining atmospheric fluorides are valuable for making an evaluation of the seriousness and extent of any fluoride air pollution problem.

Rapid methods for the determination of fluoride in hydrochloric acid, pickle liquor for hydrochloric acid regeneration systems, and gaseous emissions from steelmaking slags, using a fluoride ion-selective electrode, are presented. A single determination down to 1 ppm including standardization can be completed in hydrochloric acid in about 5 min permitting easy monitoring of incoming shipments. Fluoride contents in the gaseous emissions down to 0.01 ppm are readily determined after absorption in sodium hydroxide solution.
