There are many methods for detecting chlorine dioxide in drinking water, such as current titration, iodometric titration, ultraviolet-visible spectrophotometry, etc. The principle of visible spectrophotometry is that chlorine dioxide in water reacts with N,N-diethyldiphenylamine (DPD) to produce a pink color, which is then quantified through colorimetry at a wavelength of 528 nm, or it can be detected directly using a chlorine dioxide detector
