WebJan 1, 2008 · During the Fenton reaction, ferrous ions can quickly react with H 2 O 2 to produce hydroxyl radicals and ferric ions ( k = 70 M −1 s −1) [6], which will then be reduced by the dye to ferrous ions again. Meanwhile, ferric ions can also react with H 2 O 2, producing hydroperoxide radicals which cause a second decomposition process for the dye.
