Kinetics of oxidation of indigo carmine (IC) by sodium hypohalites, NaOX (X = C1 or Br), in alkaline buffer of pH 9-11 has been studied spectrophotometrically at A = 610 nm. The experimental rate law obtained is - ## d[IC]/dt = k[OX-][IC][OH-1" where z < 1. Variation of ionic strength or dielectr

## Abstract The degradation of the dye indigo carmine in aqueous solution induced by two oxidative processes (H~2~O~2~/iodide and O~3~) was investigated. The reactions were monitored by electrospray ionization mass spectrometry in the negative ion mode, ESI(βˆ’)‐MS, and the intermediates and oxidatio

A kinetic study of uncatalyzed and Ru(II1) catalyzed oxidation of indigo carmine(1C) (disodium 3,3'-dioxobi-indolin-2,2'-ylidene-5,5'-disulphonate) by iodate ion in aqueous sulphuric acid solution is reported. The uncatalyzed reaction order was found to be four; one each with respect to IC and iodat
