Abstract
The mechanism of peroxide decomposition involves: interconvertion of two equally active redox states: (Mn 2+, Mn 2+) and (Mn 3+, Mn 3+) states. Various inorganic anions such as Cl − or HPO − 4 inhibit catalase activity by binding to the (Mn 2+, Mn 2+). This inhibition can also be observed following reduction of the (Mn 3+, Mn 3+) states to (Mn 2+, Mn 2+) by peroxide. The (Mn 3+, Mn 4+) state, which can be formed by periodate oxidation, does not interact with these anions and is inactive in peroxide decomposition. The (Mn 2+, Mn 3+) state, which forms in a minority of centers by auto-oxidation, also appears not to participate in a major way in peroxide decomposition.
