Selective determination of paracetamol and acetylsalicylic acid on electrode modified with a mixed-valent film of ruthenium oxide-ruthenium cyanide

Catalytic activity exhibited by a mixed-valent film of ruthenium oxideruthenium cyanide deposited on the surface of a glassy-carbon electrode in electrooxidation of paracetamol and acetylsalicylic acid was used to develop a high-sensitivity selective method for determination of these compounds in the case of their joint presence under flow-injection conditions.
