“…1,2 These minerals interchange uoride ions when exposed to water, releasing uoride into water sources around the globe. [3][4][5] Fluoride exposure is highly dependent on geographical area. A primary source for uoride exposure is drinking water, 6 with 75-90% of uoride exposure in humans related to consumption of high uoride levels in natural and uoridated water.…”

“…Regarding the aluminum malachite green complex, fluoride can decrease its absorbance at 622 nm. It was concluded that the aluminum chrome azurol B complex can be used as a sensitive reagent, albeit with low selectivity, while the aluminum malachite green complex can be used as a fluoride reagent at concentrations above 1.5 × 10 −5 M. The same authors [109] developed a simple test kit for the determination of fluoride in drinking water using a polymeric aluminum complex of 5-(2-carboxyphenylazo)-8-hydroxyquinoline impregnated paper, utilizing a small hand-held Arsenator instrument. The reaction of fluoride with the complex on an impregnated paper caused a color change due to the release of the free ligand with red color, which is related to fluoride's concentration.…”

In recent years, there has been an increase in public perception of the detrimental side-effects of fluoride to human health due to its effects on teeth and bones. Today, there is a plethora of techniques available for the removal of fluoride from drinking water. Among them, adsorption is a very prospective method because of its handy operation, cost efficiency, and high selectivity. Along with efforts to assist fluoride removal from drinking waters, extensive attention has been also paid to the accurate measurement of fluoride in water. Currently, the analytical methods that are used for fluoride determination can be classified into chromatographic methods (e.g., ionic chromatography), electrochemical methods (e.g., voltammetry, potentiometry, and polarography), spectroscopic methods (e.g., molecular absorption spectrometry), microfluidic analysis (e.g., flow injection analysis and sequential injection analysis), titration, and sensors. In this review article, we discuss the available techniques and the ongoing effort for achieving enhanced fluoride removal by applying novel adsorbents such as carbon-based materials (i.e., activated carbon, graphene oxide, and carbon nanotubes) and nanostructured materials, combining metals and their oxides or hydroxides as well as natural materials. Emphasis has been given to the use of lanthanum (La) in the modification of materials, both activated carbon and hybrid materials (i.e., La/Mg/Si-AC, La/MA, LaFeO3 NPs), and in the use of MgO nanostructures, which are found to exhibit an adsorption capacity of up to 29,131 mg g−1. The existing analytical methodologies and the current trends in analytical chemistry for fluoride determination in drinking water are also discussed.

“…For example, fluoride (F – ) at about 1 mg L −1 concentration has many favorable effects on the body, including preventing tooth decay and treating osteoporosis . However, higher levels of F – in water and food are of health concerns . Dental and skeletal fluorosis has been reported in people who consume drinking water containing high levels of fluoride (5 mg L −1 ) .…”

Gold and silver nanoparticles (NPs) are shown to exert a positive effect on the chemiluminescence (CL) reaction of permanganate aldehydes. Interestingly, between various shapes examined, Au nanoprisms have the highest beneficial effect. This effect is even more notable in the presence of sodium dodecyl sulfate (SDS) surfactant. UV-vis spectra and transmission electron microscopy were used to characterize the NP shapes and sizes. Furthermore, it was observed that iron(III) ions can slightly increase CL emission of this system. This intensification is very effective in the presence of fluoride ions (F(-)). These observations form the basis of the method for the high sensitive determination of F(-) in the 6-1200 nmol L(-1) concentration range, with a detection limit of 2.1 nmol L(-1). The proposed method has good precision and was satisfactorily used in the selective determination of low concentrations of fluoride ion in real samples.
