Abstract

Hydrogen peroxide (H(2)O(2)) generated from the manganese(II) catalysed reduction of dioxygen has been shown to efficiently oxidize Calmagite (3-hydroxy-4-(2-hydroxy-5-methylphenylazo)naphthalene-1-sulfonic acid) in aqueous solution at pH 8.0 and 20 +/- 1 degrees C with de-protonated Tiron (1,2-dihydroxybenzene-3,5-disulfonate, disodium salt) acting as an essential co-ligand.

摘要

由锰（II）催化还原二氧生成的过氧化氢（H₂O₂）已被证明在pH 8.0和20±1℃的水溶液中能有效氧化铬黑T（3-羟基-4-（2-羟基-5-甲基苯基偶氮）萘-1-磺酸），去质子化的钛铁试剂（1,2-二羟基苯-3,5-二磺酸钠盐）作为必需的共配体。
