Potassium Ferrate(VI) as a Highly Efficient and Environmentally Friendly Chemiluminescence Reagent in Acidic Solution

“…Analysis of the O 2 isotopic composition for the reaction in H 2 O by Chen et al suggested that the predominant pathway for water oxidation by potassium ferrate was intramolecular O–O coupling, that is, both O atoms in O 2 were produced directly from FeO 4 2– . However, their DFT calculation tended to suggest that the oxygen production was in the form of 3 O 2 , while this work proved that the oxygen release is in the form of 1 O 2 for the first time.…”

“…However, there is no report so far as to whether K 2 FeO 4 can also produce 1 O 2 and give rise to a CL reaction upon its relaxation to 3 O 2 . Although the ferrate­(VI) ion has been used to oxidize luminol to produce CL in alkaline solution, − the light emission was resulted from luminol (λ max = 425 nm). Hence, the CL reaction between K 2 FeO 4 with various inorganic and organic compounds has not been exploited so far.…”

Electrogenerated ferrate(VI) for CE–chemiluminescence detection to determine benzenediol isomers

“…Over the last two decades, ferrate(VI) has been widely investigated as the oxidant in environmental remediation [19], as catalyst in organic synthesis [20], and more recently as cathodic charge storage material [21]. Stupin et al [22] reported that the mixing of the solid sodium ferrate(VI) and luminol solution in alkaline medium can generate a strong, lasting CL signal. They also found that certain d-metals and surfactants can affect the CL signal.…”
