“…The spectrophotometric determination of fluoride is still largely adopted for reasons of precision and reproducibility. [1][2][3][4] In this work, it was found for the first time that a blue ternary complex between Zr(IV), p-methyldibromoarsenazo (DBM-AsA) and F 2 is easily formed in the presence of hydrochloric acid at room temperature and has a maximum absorption wavelength at 635 nm. DBM-AsA, except for being used in the determination of some rare earth metals such as Th and Ce, has not attracted much attention up till now.…”

Minimization of the background arising from the capillary wall is of extreme importance in laser induced fluorescence on-column detection for capillary electrophoresis. A sensitive confocal fluorescence detection scheme is described. The intense capillary wall background light was effectively rejected by an adjustable precision slit in a confocal configuration. Rhodamine 640 was used as a standard fluorophore. Detection linearity was demonstrated over four orders of magnitude of concentration and the concentration detection limit was 3.38 x 10(-11) M.

“…In the present study, we have attempted to use In-ARS complex for sensing of fluoride ion. There are several literature reports based on metal-ARS complex that can be used for such application (Sathish et al 2007;Xu et al 2004;Cardwell et al 1988;Yasuda and Lambert 1958).…”

The work discusses about the synthesis of indium-alizarin red S complex followed by its application toward the sensing of F¯ ion. At first, the interaction between indium and alizarin red S dye was studied at three different pH medium, pH 4, 7 and 9, of which pH 7 gave the best result. The indium-alizarin red S complex so obtained was then utilized for the ratiometric sensing of fluoride ion using absorption spectroscopy with variation of temperature. The lowest limit of detection (0.040 mM) was obtained at 313 K. The mechanism for the sensing of F¯ ion was then investigated using isothermal titration calorimetry. The endothermic nature of the interaction between F¯ ion with indium-alizarin red S complex shows temperature dependence on the sensing experiment. At the end, the utility of the technique toward natural sample was also examined. The present work reports a simple, rapid and efficient detection of fluoride anion in environmental water samples.
