The Radiation Decolorization of Dilute Dye Solutions; Chlor Phenol Red^1,2

The Radiation Chemistry Of Organic Substances

“…As might be expected, oxidation occurs at the central C=C double bond, as shown by the fact that the products include isatin-5-sulfonic acid (446). The rate of bleaching of chlorphenol red is also higher in aerated than in deaerated solution (616). Possibly in this case reduction of the negative dye ion is difficult (compare fluorescein above).…”
