A simple method for detection of low concentrations of fluoride in drinking water

•A simple, reagent-free, non-colourimetric method for detection of fluoride in water at drinking-water-relevant 0–5 mg L−1 concentration range.•Optical fibre tip coated with aluminum by sputter deposition is degraded in the presence of fluoride, decreasing internal reflection of infrared light.•Kine...
