How to measure chlorine dioxide in water

WebA method for measuring free chlorine is via the DPD method, typically at the 0.1-2.0 mg/L range. The DPD indicator and buffer solution are mixed with the chlorine-containing water samples, forming a pink solution. Using a series of colours from a colour wheel, it is possible to approximate free chlorine concentration in a sample. WebChlorine dioxide can also be determined electrochemically. Such methods fulfill all the necessary goals expected of analytical chemis-try. They are highly sensitive, selective, highly accurate and correct. Chlorine dioxide can be selectively determined from the concentra-tion of 0.3 mg.l-1 using a rotary membrane electrode. Neither hypo-
