Titrimetric determination of iron (II) with potassium bromate in a strong phosphoric acid medium with a potentiometric end-point

  • G. Gopala Rao

The use of a strong orthophosphoric acid medium enables a direct titration of iron(II) to be made at room temperature (in an inert atmosphere) with potassium bromate using a potentiometric endpoint. Various organic substances like oxalate, tartrate, citrate, sucrose and glucose do not interfere. The method is, therefore, likely to be important for the determination of ferrous and ferric iron in pharmaceutical products.

Die direkte Titration von Eisen(II) mit Kaliumbromat kann in stark phosphorsaurer Lösung bei Zimmertemperatur (in inerter Atmosphäre) mit potentiometrischer Endpunktsbestimmung durchgeführt werden. Organische Verbindungen wie Oxalat, Tartrat, Citrat, Saccharose und Glucose stören nicht. Das Verfahren könnte daher bei der Eisen(II)- und Eisen(III)-bestimmung in Arzneimitteln Verwendung finden.
