Abstract

Methods for the determination of fluorine in a variety of matrices are reviewed with particular attention to thosetechniques which arewidely adapted as routine methods. The fluoride con-sensitive electrode is a very successful potentiometric titration technique for the determination of fluoride in aqueous solution and it?s largely replaced the various colorimetric methods formerly used. However it is apparent that the rapid development of ion-chromatography with its advantage of simultaneous multi ion determination is introducing a new phase into fluoride analysis. The aim and purpose of this review to describe the analytical methods that are available for detecting, measuring, and/or monitoring fluorides, hydrogen fluoride and fluorine and its monitories. The intent is not to provide an exhaustive list of analytical methods. Rather, the intention is to identify well- established methods that are used as the standard methods of analysis many of the analytical methods used for the environmental samples are the methods approved by the federal agencies and organizations such as EPA and National institute of occupational safety and Health (NIOSH). Other methods presented in this review are these that are approved by groups such as the Association of Official Analytical Chemists (AOAC) and the American Public Health Association (APAA). Additionally, analytical methods are included that modify preciously used methods to obtain lower detection limits and/or to improve accuracy and precision.
