The ferryl generation by fenton reaction driven by catechol
(2023)
The Fenton and Fenton-like reactions are based on the decomposition of hydrogen peroxide catalyzed by Fe(II), primarily producing highly oxidizing hydroxyl radicals (HO∙). While HO∙ is the main oxidizing species in these ...
Voltammetric study of the redox chemistry of 2,3-dihydroxy-quinoxaline and its zinc complexes in non-aqueous medium
(PERGAMON-ELSEVIER SCIENCE LTD, 1998)
The electrochemical behaviours of 2,3-dihydroxy-quinoxaline (2,3-DH(2)Qx) and the complex species formed with zinc(II) have been studied in non-aqueous media. Using dimethylsulphoxide or N,N-dimethylformamide as solvents ...
Raman, IR, UV-vis and EPR characterization of two copper dioxolene complexes derived from L-dopa and dopamine
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The anionic complexes [Cu(L(1-))(3)](1-), L(-) = dopasemiquinone or L-dopasemiqui none, were prepared and characterized. The complexes are stable in aqueous solution showing intense absorption bands at ca. 605 nm for ...
Dependence on the production of the ferril (Fe4 +) and hydroxyl radical (HO ∙) species in the Fenton reaction driven by catecholDependence on the productión of the ferril (fe4 +) and hydroxyl radical (ho ∙) species in the fenton reactión driven by catechol
(2018)
The main oxidant species in Fenton and Fenton-like reaction driven by catechol are HO∙ and Fe(IV). The prevalence of these species are dependent of reaction conditions. HO∙ production has been broadly studied in Fenton and ...
Mechanistic Implications of Zinc(II) Ions on the Degradation of Phenol by the Fenton Reaction
(SOC BRASILEIRA QUIMICASAO PAULO, 2013-08-02)
A study of the interference of Zn2+ ions on phenol degradation by Fenton reaction (Fe2+/Fe3(+) + H2O2) is reported. One of the first intermediates formed in the reaction, catechol, can reduce Fe3+ to Fe2+ and, in the ...
Mechanistic implications of zinc(II) ions on the degradation of phenol by the fenton reaction
(Sociedade Brasileira de Química, 2012)
A study of the interference of Zn2+ ions on phenol degradation by Fenton reaction (Fe2+/Fe3+ + H2O2) is reported. One of the first intermediates formed in the reaction, catechol, can reduce Fe3+ to Fe2+ and, in the presence ...
Toxic effects of apomorphine on rat cultured neurons and glial C6 cells, and protection with antioxidants
(Biochemical Pharmacology, 2001-01-01)
Many catechol derivatives are currently used as drugs, even if they produce reactive oxygen species that may cause tissue damage. Among them, apomorphine, a potent dopamine agonist, displays efficient anti-parkinsonian ...
