Formation of iron(VI) in ozonalysis of iron(III) in alkaline solution

Here we report the formation of iron in hexavalent state, FeVI O42 - in ozonalysis of iron(III) in alkaline medium. The formation of tetrahedral FeVI O42 - ion is confirmed by UV-Visible an

The electrochemical generation of ferrate at porous magnetite electrode

In this work, ferrate(VI) was generated by the electrochemical oxidation of porous magnetite electrodes, made by melting pure magnetite grains. Pretreatment of the anode by cathodic polarization was necessary for ferrate(VI) generation and the achievement of high current efficiency. A electrolyte composition was found to be 16M NaOH. In this electrolyte, the effect of anode current density J on Fe(VI) synthesis rate, current efficiency, and internal cell temperature were studied. An optimum result was obtained at J = 3.3mAcm-2, 30°C in 16M NaOH for 5h.

Oxidation of thiocyanate by iron(V) in alkaline medium

The oxidation of thiocyanate (SCN-) by iron(V) (Fe(V)) was studied as a function of pH in alkaline solutions by a premix pulse radiolysis technique. The reaction precedes via a two-electron oxidation, which converts Fe(V) to Fe(III). The rates decrease with an increase in pH. The reactivity of diprotonated Fe(V) species, H2FeO4- with SCN- could account for the decease in rate with increasing pH. The oxidation of thiocyanate by iron(V) (Fe(V)) was studied as a function of pH in alkaline solutions by a premix pulse radiolysis technique. The rates decrease with an increase in pH. The rate law for the oxidation of SCN- by Fe(V) was obtained as -d[Fe(V)]/dt = k10{[H+]2/([H+]2 + K 2[H+] + K2K3)}[Fe(V)][SCN -], where k10 = 5.72 ± 0.19 × 106 M-1 s-1, pK2 = 7.2, and pK3 = 10.1. The reaction precedes via a two-electron oxidation, which converts Fe(V) to Fe(III). Thiocyanate reacts approximately 103× faster with iron(V) than does with iron(VI).
