abstract = "The dark reduction kinetics of micromolar concentrations of Fe(III) in aqueous solution were studied in the presence of millimolar concentrations of ferrozine (FZ) over the pH range 4.07.0. A pseudo-first-order kinetics model was used to describe Fe(III) reduction at pH 4.0 and
5.0, and the reduction rate decreased with increasing pH or initial Fe(III) concentration. A more molecular-based kinetics model was developed to describe Fe(III) reduction at pH 6.0 and 7.0. From this model, the intrinsic rate constants (k
1) of Fe(III) reduction by FZ in
the dark were obtained as 0.133\textpm0.004M1 s1 at pH 6.0 and 0.101\textpm0.009M1 s1 at pH 7.0. It was also found in this model that a higher pH, a higher concentration of Fe(III),
a lower concentration of FZ and less incubation time led to a lower fraction of Fe(III) reduction by FZ in the dark.",
