Abstract The catalytic activity of Mn(+II) and Mn(+III) in decomposing hydrogen peroxide was studied by using DTPA as the only stabilizer. It was found that the addition of DTPA to a Mn(+II) containing system is more effective than if it is added to a Mn(+III) containing system. To decrease the catalytic effect of Mn(+III), sodium borohydride and DTPA under an acidic condition were considered to reduce Mn(+III) to Mn(+II). The effect of pH on using DTPA to decrease Mn-induced peroxide decomposition is discussed.
