Abstract
Electroreduction of etramethyltetra-3,4-pyridinoporphyrazinocobalt(II) in aqueous buffer phosphate solution leads to the deposition of an in soluble tetrapyridinoporphyrazinocobalt(I) phthalocyanine film on the highly oriented pyrolytic graphite (HOPG) electrode. This modified HOP G electrode has been further coated with Nafion or Tosflex ion-exchang e membranes and used in the determination of concentration of sulfide ion and 2-mercaptoethanol by direct potentiometry.
