Abstract
A method for measuring bromate ion includes: a first step of introducing a test water sample to an anion exchanger that selectively absorbs bromate ions; a second step of introducing, to the anion exchanger, a hydrochloric acid solution containing a fluorescent substance, a fluorescence intensity of which is changed by the coexistence of bromate ions; a third step of measuring the fluorescence intensity of the fluorescent substance contained in the hydrochloric acid solution discharged from the anion exchanger; and a fourth step of using a calibration curve, which shows a relationship between the fluorescence intensity of the fluorescent substance and the concentration of the bromate ions, to calculate the concentration of the bromate ions that corresponds to the measured fluorescence intensity.
