Chlorine dioxide is determined from its absorbance as the coloured product (Xmax = 490 nm) of its reaction with tyrosine [48]. Chlorine dioxide has been found to reduce the absorbance of Acid Chrome Violet K [49]. Spectrophotometric methods of determining CIO2 with the use of Chlorophenol Red have been proposed [50,51]. A scheme for analysing mixtures of Cf, CIO, CIO2, ClO.i, CIO4 , and CIO2 using spectrophotometric and other methods has been devised [52]. 

Key CL, chemiluminescence UV, ultraviolet IDS, indigo-5,5 -disulfonate ITS, indigo-5,5, 7-trisulfonate ACVK, Acid Chrome Violet K (Alizarin Violet 3R) n.a., For batch methods, sampling time (s) is shown in parentheses. 

As in the case of indigosulfonates. Alizarin Violet 3R (Acid Chrome Violet K) loses its color on reaction with ozone and chlorine dioxide. Ozone can be determined from the decrease in absorbance at 548 nm after mixing with a sample solution. This method is less sensitive than the indigo methods. Chlorine, hypochlorite, chlorite, and chlorate do not interfere. While chlorate(in) can also be determined by this method, it does not coexist with ozone in treated waters.
