Microdetermination of chloride and azide by sequential titration

Microchimica Acta volume 59, pages 46–53 (1971)Cite this article

Summary

A rapid method for the microdetermination of chloride and azide by sequential titration with silver nitrate in 80%p-dioxane is described. A chloride-selective indicator electrode and a single-junction reference electrode are used with an expanded-scale pH meter to monitor the emf. For the determination of chloride only (in the presence of azide), the potentiometric titration with mercuric perchlorate is used. A twofold excess of azide does not interfere in this determination.

Zusammenfassung

Ein schnelles Verfahren zur Mikrobestimmung von Chlorid und Azid durch Sequenztitration mit Silbornitrat in 80%igem p-Dioxan wurde beschrieben. Eine chloridspezifische Indikatorelektrode und eine Bezugselektrode mit Einzelverbindung wurden mit einem pH-Meter mit gedehnter Skala zur Potentialmessung verwendet. Für die Chloridbestimmung allein (in Gegenwart von Azid) wurde potentiometrisch mit Quecksilberperchlorat titriert. Ein zweifacher Überschuß von Azid stört die Bestimmung nicht.
