الملخص الإنجليزي

An indirect method for the estimation of fluoride ion has been developed.The method is based on the bleaching action of fluoride ion on the color of Ti (IV)with 2-hydroxy-1-(2-hydroxy-4-sulfo-1-naphthylazo)-3-naphthanic acid (HHSNNA) complex with proportional decrease of absorbance.

Therefore,the decrease in color intensity is proportionalto the concentration of fluoride ion.

Molar absorptivityis 0.1166×104 l.

mol-1.cm-1 atwavelength 685 nm.

Beer's lawis obeyed over the concentration range of 0.2-4 μg/ml.The proposed method is applied successfullyto determine fluoride ion in different real water samples andpharmaceutical preparations (Tablets).

The proposed method is compared favorably with Eriochrome cyanine R – Zirconium method.
