  • Method of Measuring Fluoride in Fluxes Using the Fluoride Ion-Selective Electrode
    Publication number: 20070082404
    Abstract: A method for analyzing fluoride in fluxes comprises the steps of placing the flux into an aqueous solution. Chelating agents are added to the aqueous flux solution to form a chelated aqueous flux solution. The chelating agents are selected from the group consisting of ammonium citrate dibasic, ammonium tartrate dibasic, citric acid, ethylene diamine, disodium-EDTA solution, and sodium chloride. And, a potentiometric analysis is performed on the chelated aqueous flux solution using the plurality of control standard solutions for determining the fluoride content of the flux.
