  • Title: Application of redox reactions in spectrophotometry-I The iron(III)/1,10-phenanthroline complex as a reagent for the determination of some anions and organic compounds.
    Author: Koch S, Ackermann G.
    Journal: Talanta; 1992 Jun; 39(6):687-91. PubMed ID: 18965438.
    Abstract:
    It is shown that the complex of iron(III) with 1,10-phenanthroline(phen) is suitable as a reagent for determination of some anions and organic compounds. By a redox reaction with the analytes the reagent forms the intensely coloured chelate [Fe(phen)(3)](2+), which is extractable as an ion-association complex with a suitable counter-ion and allows the development of sensitive spectrophotometric methods of determination. Besides the fundamentals, some remarks on analytical applications are given.
