reduction/oxidation indicators are colorimeter ew3AV
reduction/oxidation indicators are colorimeter reagents that produce a particular color change at a specific electrode potential. There are several organic dyes that show reversible redox reactions, such as bodipy, o-dianisidine, diphenylamine, eriogreen, phenamic acid, methylene blue, Nile blue, and 2, 2′-bipyridine that some are shown in figure 14. because of the participation of protons within the electron transfer process in most environments, redox indicators are divided into groups consistent with whether they are pH-dependent or not [79]. Lin and Suslick for the detection of triacetone triperoxide (TATP) vapor in the range of 50 ppb to ppm, a color sensor array which includes o-dianisidine, diphenylamine, N-phenyl-1, 4 -phenylenediamine, N, N′-diphenyl- 1, 4-diphenyl diamine, and Lissamine green B were developed the usage of a solid acid catalyst that permits the degradation of TATP into more detectable species. This array was able to detect TATP vapor concentrations below 2 ppb and differentiate TATP from different chemical oxidants. [216]
