Detection of Fluoride Ion in Water: an Optical Approach and Review

This paper presents the review on different concepts of fluoride detection techniques and technologies in water. At high concentration Fluoride is toxic to humans. When humans are exposed to fluoride-containing water, they can suffer from health problems, such as dental disease. Drinking water is the most consumed beverages. For humans beverages aresignificant sources of fluorides. Consistent evaluation of the element’s content in the large variety of existing drinking water requires the small margin between suitable and overdose fluoride levels in the human body.Due to the collection of drinking water from public sources such as wells and tap-stands, also during its storage in the home, drinking-water can become polluted. There are various techniques to determine Fluoride ion in water such as Ion selective electrode, Colorimetric Technique, UVVis Technique, Fluorescence Technique. This paper gives comparative study of all these methods to detect Fluoride. This review will also give different study about optical approaches to detect Fluoride.
