Ion-Selective Electrode for the Determination of Iron(III) in Vitamin Formulations
A coated graphite-epoxy ion-selective electrode for iron(III), based on the ion-pair formed between [Fe(citrate)2]3- and the tricaprylylmethylammonium cation (Aliquat 336) in a poly(vinylchloride) (PVC) matrix has been constructed. A thin membrane film of this ion-pair, dibutylphthalate (DBPh) in PV...
