    • A method for measuring bromate ion is provided that provides high-sensitivity measurement results more simply and more quickly than conventional bromate ion measurement methods. A fluorescent substance that is quenched by coexistence with bromate ions is added to a sample 130 and the fluorescence intensity of the fluorescent substance after quenching is measured, the measured fluorescence intensity being subtracted from the fluorescence intensity of a standard sample containing no bromate ions to calculated the fluorescence intensity difference. The bromate ion concentration is calculated from the calculated fluorescence intensity difference, using a pre-determined calibration line between the fluorescence intensity difference and the bromate ion concentration.
    • 提供了一种测量溴酸根离子的方法,其比传统的溴酸盐离子测量方法更简单和更快地提供高灵敏度的测量结果。 将通过与溴酸根离子共存淬灭的荧光物质加入到样品130中,并测量淬灭后的荧光物质的荧光强度,从不含溴酸根离子的标准样品的荧光强度中减去测量的荧光强度,以计算 荧光强度差异。 使用荧光强度差异和溴酸根离子浓度之间的预先确定的校准线,从计算的荧光强度差计算溴酸根离子浓度。
