Determination of fluorine in fluoroquinolone drugs by oxygen-flask combustionand fluorine ion selective electrode;

A rapid method for determination of flouride in toothpaste by fluoride selective electrode is introduced in this paper.

MethodsWe collected the drinking water sanrples of all the administrative villages in Huaibei city and determined the contents of fluorine in water by fluoride selective electrode.

, by the standard addition method to eliminate the effects of salt, the trace fluorine in seawater was determined with fluoride ion selective electrode determing the potential in seawater at pH=6.

This paper adopted potentiometry, applied the saturated calomel electrode (SCE) as reference electrode and fluoride ion selective electrode as indicator electro.

The fluorine in ores was determinated by fluorine ion selective electrode with the limit of 0.

In this work,the fluorine ion selective electrode was used as indicative electrode,a standard calomel electrode as reference electrode to investigate the effect of surfactant SDS on the sensitivity of ion selective electrode.

Determination of sodium of salt lake by ion selective electrode method;

This paper expounds the significance of fluoride detection, and introduces some experiences of detecting the fluorine ions by using ion selective electrode method.

The analyses of fluoride by ion selective electrode method, colorimetry, ion chromatography, liquid chromatography, gas chromatography in the last few years have been introduced, and a prospect of its develo pments is also proposed.
