title: The trifluoroacetic anhydride-sodium iodide system as a reagent for determination and microdetermination of nitroxide radicals.
abstract: A trifluoroacetic anhydride-sodium iodide mixture (TFAA-I) reacts with nitroxide radicals with liberation of iodine. Since stoichiometric amounts of iodine are formed from nitroxides, the TFAA-I reagent can be applied to their analytical determination. Two procedures for the determination of nitroxides (titrimetric on mumol and spectrometric on nmol levels) are described.
