The Study of the Electrochemical Behaviour of Metalo-Porphyrins with Co(II) and Co(III). Nitrite-Selective Electrode Based on <5,10,15,20-Tetraphenyl-21H,23H-porphyrinato-N21, N22, N23, N24> Co(III) Chloride

Abstract:

The purpose of this study was the electrochemical characterization by cyclic voltammetry of meso-tetraphenylporphyrinato Co(II) and Co(III) - (CoTPP and ClCoTPP), which were previously synthesised and characterized by UV-vis, FT-IR and 1H-NMR spectrometry. These compounds can be used as sensor materials in anion-selective liquid membrane electrodes. A nitrite-selective membrane based on ClCoTPP, as sensor material, was obtained and characterized, and the work parameters of the electrode obtained with it were established. Keywords: nitrite-selective liquid membrane electrode, meso-teraphenylporphyrinato-Co(II), meso-teraphenylporphyrinato-Co(III) chloride, cyclic voltammetry, membrane composition, selectivity
