...). The addition of a reduced transition metal, such as ferrous iron and cupric copper leads to a heterolytic decomposition with OH − and · OH as products. This is exploited in the so called Fenton reaction (Eqn. 9) in which hydrogen peroxide is mixed with a solution of a ferrous iron salt ( Fenton 1894...
