Reduction of iodate by hydrazine: Application of the iodide ion selective electrode to the uncatalyzed reaction

  • R. A. Hasty
Article

Summary

The reduction of iodate by hydrazine was examined by use of the iodide ion selective electrode. The rate of reduction of iodate at iodide concentrations below 5 × 10−5M is controlled by the direct reduction by hydrazine. At higher iodide concentrations, the rate of reduction of iodate is controlled by the reduction of iodate by iodide with the subsequent reduction of iodine by hydrazine. Application of the reaction to the determination of μg quantities of iodine is discussed.

Zusammenfassung

Die Reduktion von Jodat mit Hydrazin wurde mit Hilfe einer jodid-spezifischen Elektrode untersucht. Das Ausmaß der Jodatreduktion bei Jodid-konzentrationen unter 5·10−5 Mol/l wurde durch direkte Reduktion mit Hydrazin kontrolliert. Bei höheren Jodidkonzentrationen wurde das Reduk-tionsausmaß des Jodats mit Hilfe der Jodat-Jodid-Reaktion und erst dann durch Reduktion des Jodids mit Hydrazin kontrolliert. Die Anwendung auf die Bestimmung von μg-Mengen Jodid wurde diskutiert.
