“…Especially, it is impossible to determine fluorine using its atomic spectrum since its main resonance line is located at 95 nm. As a method of determination of fluorine by atomic absorption, indirect spectrometry using Zr and Mg atomic absorption was reported by Bond et al (1). However, this method is rather insensitive and inconvenient for practical use.…”

The diatomic molecule of aluminum monofluoride, AIF, gives a sharp absorption band spectrum at 227.5 nm in both flames and a carbon rod furnace. The absorption intensity is high enough so that it can be used for a sensitive analytical method of fluorine determination. The best sedtivity observed Is 0.021 ng of fluorine with the carbon rod furnace, which Is the best so far reported for this element and Is also superior to that obtained with the N20-C2H2 flame, Le., 24 pg F/mL. An excess aluminum solution is applied first to the furnace before the fluorine containing sample is pipetted, so that the AIF molecule is effectively formed inside the furnace. A certain amount of strontium and nickel Is found to enhance the signal with decreasing the background. The method has been successfully applied to biological samples and also to organofluorine compounds.

“…of refractory compounds (1)(2)(3)(4); the change in the volatility of the matrix including the analyte metal (5)(6)(7)(8); and the enhancement of metal ionization (9)(10)(11)(12). Particularly, Haraguchi et al suggested that the acid interference might be due to the formation of diatomic molecules between the analyte metal and its coordinating atoms (13,14).…”

“…Until now, many analytical methods including inductively coupled plasma, atomic emission spectrometry, atomic absorption spectroscopy, electrochemical methods, absorption and emission spectroscopy have been reported for detection of uoride anion. [8][9][10][11][12] Among them, the uorescent technique has been attracted particular attention for its low-cost, high sensitivity and easy operation. [13][14][15][16][17] Thus, many uorescent uoride probes based on different interaction mechanisms, including hydrogen bonding, [18][19][20][21][22][23] Lewis acid complexation [24][25][26][27][28] and desilylation reaction, [29][30][31][32][33] have been developed.…”
