Direkte elektrometrische Bestimmung des Fluorid-Ions

Die Arbeitsweise einer Fluoridionen-empfindlichen Elektrode wurde gepruft und der Einflus von Fremdsubstanzen auf die Potentiale untersucht. Die Storungen konnen durch Maskierung, Pufferung oder durch eine Auswertmethode vermindert werden.

Abtrennung und gas-chromatographische Bestimmung von Fluoridspuren

Spuren an Fluorid konnen aus wasrigen Losungen mit (C2H5)3SiCl in m-Xylol oder mit (C6H5)4SbOH in CH2Cl2 ausgeschuttelt werden. Von verschiedenen untersuchten Mitfallungsreaktionen erwies sich die Adsorption an Hydroxylapatit als am gunstigsten.
