中文摘要：In hydrochloric acid medium,a highly sensitive fluorescence quenching method was developed for the determination of ClO2,based on its oxidation of I to I3 by ClO2 and the further reation of I3 with rhodamine 6G to form the ion-association complex.The detection Iimit is 0.8 μg/L.The linear range of calibration curve is 0-80 μg/L.It has been applied to the determination of trace ClO2 in tap water with satisfactory results.
