A sensor for the determination of fluorine was constructed using an Ag-electrode and the exoskeleton of Antarctic krill from which endogenous fluorine had been previously removed. The principle of the proposed sensor is based on the membrane potential difference being pro-duced by the recombination of fluorine on the exoskeleton of Antarctic krill. A linear relationship was observed between the rate of the increase in the output of the sensor and the concentration of fluorine (0.5-5ppm) when the sample solution was stirred at 1000rpm and 25°C. Fluorine contents in raw and dried leaves of Japanese teas were determined by the proposed sensor and a conventional method. Good comparative results were obtained between the values determined by both methods. One assay could be completed within about 30min.
