Application of Fenton reaction for nanomolar determination of hydrogen peroxide in seawater

Influence of magnetic field on the adsorption of organic compound by clays modified with iron

“…The iron phases identified in this material were maghemite and hematite, where the oxidation state of iron is three (Fe III). However, it has been reported that the decomposition of H 2 O 2 in the presence of Fe III was favored by the reduction of Fe III to Fe II in the presence of H 2 O 2 (Olasehinde et al, 2008;Tireli et al, in press) giving the classical Fenton reaction sequence that occurs very quickly with the Fe II/H 2 O 2 system. A portion of the FeMAG structure had collapsed but the iron species were still present and possibly more accessible; it was deposited under the surface of the material and confirmed by XRD (Fig.…”

Sensing of hydrogen peroxide and glucose in human serum via quenching fluorescence of biomolecule-stabilized Au nanoclusters assisted by the Fenton reaction

“…It is well known that H 2 O 2 can generate extremely oxidative hydroxyl radicals in the presence of Fe 2+ , so called Fenton reaction, which has been widely applied in wastewater treatment. 36 Herein, we take advantage of Fenton reaction to accelerate uorescence quenching of Au NCs in the presence of H 2 O 2 to sensitive and selective detect H 2 O 2 and glucose (Scheme 1). Aer 20 mM H 2 O 2 was added to the Au NCs-Fe 2+ -HCl system, the corresponding emission intensity of the sensing system was completely quenched (Fig.…”

“…In the present case, Fe 2+ served as a catalyst to disproportionate H 2 O 2 to produce hydroxyl radical (cOH) through the so-called Fenton reaction. [36][37][38] The produced radical species are extremely reactive which can oxidize not only the thiol group of the protecting agent, but also the Au atoms in Au NCs. Therefore, sensitive detection of H 2 O 2 can be achieved.…”

Photoformation of OH radical in water-extract of atmospheric aerosols and aqueous solution of water-soluble gases collected in Higashi-Hiroshima, Japan

“…The addition of DFOM produces a stable and strong complex with Fe (III) that results in suppression of the photo-Fenton reaction (Nakatani et al, 2007). The initial concentration of H 2 O 2 was determined according to the method described by Olasehinde et al (2008) Nakatani et al, 2001).…”
