Electrode with electrochemically deposited N,N',N'',N'''-tetramethyltetra-3,4-pyridinoporphyrazinocobalt(I) for detection of sulfide ion
摘要：
Electroreduction of N,N',N'',N'''-tetramethyltetra-3,4-pyridinoporphyrazinocobalt(II) in aqueous buffer phosphate solution leads to the deposition of an insoluble tetrapyridinoporphyrazinocobalt(I) phthalocyanine film on the highly oriented pyrolytic graphite (HOPG) electrode. This modified HOPG electrode has been further coated with Nafion or Tosflex ion-exchange membranes and used in the determination of concentration of sulfide ion and 2-mercaptoethanol by direct potentiometry.
