Fluorescence Determination of ClO2 with CdTe Dots

Article Preview

Abstract:

In pH 8.0-9.1 NH4Cl-NH3 buffer solutions, the CdTe dots in different size appear fluorescence peak at 632 nm-748 nm. Upon addition of ClO2, the fluorescence peak quenched linearly. The quenching fluorescence intensity is linear to the ClO2 concentration. Thus, a sensitive and simple fluorescence method was proposed for the determination of ClO2 in water sample.
