Abstract：In acidic sodium acetate-HCl buffer solution containing KI, Rhodamine B(RhB) has a fluorescence peak at 580 nm. When ClO-2 exists fluorescence quenching occur. The fluorescence quenching intensity is linear with the concentration of ClO-2 in the range of 0.021 8-0.51 μg·mL-1. Based on this, a new, simple, sentisive fluorescence method has been proposed for the determination of ClO-2 in water, with satisfactory results.
