A fluorometric method for determining trace quantities of fluoride

  • Published:
Microchimica Acta Aims and scope Submit manuscript

Summary

A very selective method has been developed for the determination ofμg quantities of fluoride based on the fluorescence quenching by fluoride of the zirconium-flavonol chelate. The fluorescence intensity is read at 460 nm. The reduction in fluorescence intensity caused by the fluoride is a measure of the fluoride concentration present.

Zusammenfassung

Eine sehr selektive Methode zur Bestimmung von Mikrogrammengen Fluorid mittels Fluoreszenzlöschung von Zirkonium-Flavonol-Chelat wurde ausgearbeitet. Die Messung erfolgt bei 460 nm. Die Herabsetzung der Fluoreszenzintensität entspricht der Fluoridkonzentration.
