Study of the oxidation kinetics of nitrite ions by potassium ferrate(VI)

Abstract

2 4 FeO − with harmful organic and inorganic substances in an acidic, neutral and weakly alkaline condition. The kinetics and products of the oxidation of caffeine by acid-activated ferrate(VI) are described in [1]. The oxidation processes of pentachlorophenol [2] and phenol [3] by ferrate(VI) in neutral and weakly alkaline condition are offered. The kinetics and mechanism of ferrates(Fe(VI), Fe(V), and Fe(IV)) oxidation of iodide with the formation of triiodide at pH 5-10.3 [4] are present

Reaction of Amino Acids with Ferrate(VI): Impact of the Carboxylic Group on the Primary Amine Oxidation Kinetics and Mechanism

“…67 The former is oxidized to nitroalkane (9), 66 while the latter is oxidized to nitrite (10), 21 which is further oxidized to nitrate (12) (Scheme 1). 68 Nitroalkane can also be oxidized to nitrite (11), but this reaction was previously found to be quite slow at pH 7 and may not be a significant reaction pathway for nitrite/nitrate formation. 21 N-Hydroxylation has been shown to be a relevant pathway in the Fe(VI) oxidation of phenethylamine but only at pH 7 (33% in phosphate).…”

On the Origins of Some Spectroscopic Properties of “Purple Iron” (the Tetraoxoferrate(VI) Ion) and Its Pourbaix Safe-Space

“…Results are plotted, Figure 14 . Carr et al [ 141 ] set a good example in ferrate(VI) research when they took into account the parallel decomposition of Fe VI O 4 2− during the oxidation of nitrite NO 2 − ions. Control experiments were done separately to determine the rate of self-decomposition of Fe(VI) at pH = 14.9, at a solution temperature of 20 °C.…”

“…Results are plotted, Figure 14. Carr et al [141] However, the number of OH − ions present in the hydration sheath of the Fe(VI) ani be limited by electrostatic repulsion. Do pH values drop so rapidly during redox re that so much caustic soda is required?…”
