Article Synopsis
- A new method was developed to detect trace amounts of chlorine dioxide in water, using rhodamine dyes that change fluorescence in the presence of chlorine dioxide.
- The best-performing dye was rhodamine S, capable of detecting chlorine dioxide concentrations as low as 0.0030 µg/mL, within a linear range of 0.0060 to 0.450 µg/mL.
- This method demonstrated good selectivity, as other chlorine compounds did not interfere with the detection process, and it successfully analyzed both synthetic and real water samples.

S2- and Ag+ form stable Ag2S nanoparticles in the presence of sodium dodecyl sulphate (SDS). It exhibits a strong resonance scattering peak at 470 nm and a strong fluorescence peak at 470 nm when excitation wavelength is at 200 nm. The effects of TAA and Ag+ concentration on the fluorescence intensities are consistent with those on the resonance scattering signals.
