The oxidation of Fe(II) at nanomolar levels with O 2 , H 2 O 2 and their mixtures has been studied and a kinetic model has been applied to describe the experimental results. A first order pH dependence is obtained when the H 2 O 2 controls the oxidation, due to the large contributions of FeOH + and
