Abstract: An original attachment and application software were developed for simple fluoride analysis using a smart device such as a smartphone or tablet device, and the analytical performance of the proposed method was evaluated. Using a color reaction with lanthanum/alizarincomplexone, fluoride ion was determined in the concentration range from 0.5 to 1.5 mg/L; the relative standard deviation was 5.5% at the median of the calibration curve (5 determinations). Moreover, analytical results combined with date, time, and location information were obtained in the proposed method; the analytical results were then mapped using mapping software.
