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).

Ferricyanide ions oxidize Fe(III) up to Fe(VI) in 7-11 M KOH solutions and 10-16 M NaOH solutions. The completeness of the oxidation increases with increasing alkali and ferricyanide concentrations. The presence of KNO 2, KAc, and K2

Formation of iron(VI) in ozonalysis of iron(III) in alkaline solution
Perfiliev, Yurii D.,Benko, Elena M.,Pankratov, Denis A.,Sharma, Virender K.,Dedushenko, Sergey K.

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
