Rapid Determination of Fluoride in Hydrochloric Acid, Pickle Liquor, and Gaseous Emissions

Source

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.
