Mercury oxidation in vitro by ferric compounds

Archives of Toxicology, 1982
Among the ferric compounds studied, cytochrome C, methemoglobin, lactoperoxidase, ferritin and ferric ion, in addition to catalase, had the ability to oxidize metallic mercury in the presence of hydrogen peroxide. On the other hand, hematin, the active center of catalase, did not oxidize metallic mercury.

Interactions of Ferric Ions with Olive Oil Phenolic Compounds

Journal of Agricultural and Food Chemistry, 2005
The ferric complexing capacity of four phenolic compounds, occurring in olives and virgin olive oil, namely, oleuropein, hydroxytyrosol, 3,4-dihydroxyphenylethanol-elenolic acid (3,4-DHPEA-EA), and 3,4-dihydroxyphenylethanol-elenolic acid dialdehyde (3,4-DHPEA-EDA), and their stability in the presence of ferric ions were studied.

Sternheimer Quadrupole Factors in Ferric Compounds

physica status solidi (b), 1982
AbstractExpressions for the quadrupole shielding (antishielding) factors corresponding to various types of electronic charge distributions in a solid complex are obtained by means of Sternheimer's perturbation‐numerical method generalized for the two‐centre case.

Solubilities and stabilities of ferric arsenate compounds

Hydrometallurgy, 1989
Basic ferric arsenates precipitated from hydrometallurgical liquors by hydrolysis are shown to be very insoluble over a range of pHs. The stability range (solubilities

Transformation of ferric compounds into iron oxides

International Geology Review, 1977
Ferrihydrite (2.5 Fe2O2-4.5 H2O) is an unstable colloidal mineral. It dissolves in highly alkaline solutions and is precipitated from them in the form of goethite. Jarosite is stable at very low pH but is decomposed at higher values of pH with separation of iron oxides. Experiments show that in rapid decomposition of jarosite a protohematite substance,

Photodegradation of polyethylene in the presence of ferric salt: Influence of ferric acetylacetonate on model compounds

Journal of Polymer Science: Polymer Chemistry Edition, 1978
AbstractThe influence of ferric acetylacetonate [Fe(acac)3] on the photodegradation of model compounds of polyethylene (PE) was examined. By studying electron‐spin‐resonance (ESR) spectra of photoirradiated compounds such as 1‐octene and 1,7‐octadiene, which contain carbon double bonds, Fe(acac)3 was found to accelerate the formation of allyl radical ...
