Solvent Extraction of Iron

The process to be presented makes use of a commercial mixture of highly-branched monocarboxylic acids with the trade name of "Versatic 10" (Shell). The formula may be presented as: where the total number of carbon atoms in the molecule is about 10. In short the Versatic acid will be termed RH. The organic acid RH will act as a liquid cation exchanger and may generally extract metal ions ...

Extraction of iron from plant leaves by Fe (II) chelators ...

Abstract. In the working conditions used for the extraction of iron with 1,10‐phenanthroline (o‐phe) or 2–2' Bipyridyl (Bipy) from plant material, in vitro photoreduction of ferric ions occurs. Nevertheless, iron in plant extracts was found to be independent of the illumination conditions where the sample was maintained during the extraction.
