    Abstract

    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.
