| Abstract: | Formation of superoxide ion (O2-) from the reaction of CuII(en)2 (en: ethylenediamine) with hydrogen peroxide (H2O2) was first determined spectrophotometrically by use of nitro blue tetrazolium (NBT) in aqueous solutions. From this result, it has been suggested that superoxide ion is generated as an intermediate at the first reaction step between CuII(en)2 and H2O2. |
