Voltammetry at Micro-Mesh Electrodes
Neste trabalho investigamos a voltametria em eletrodos do tipo micromesh. Em experimento de duração suficientemente curta, os eletrodods de trabalho micromesh se comportam primeiramente como uma rede de eletrodos de microbanda, seguido pelo comportamento esperado para um arranjo de eletrodos de micro-anel, independentes de difusão, com perímetro igual ao tamanho da grade. Durante eletrólise pro...
متن کاملPractical Problems in Voltammetry 3: Reference Electrodes for Voltammetry
the reactions of interest occur at the surface of the working electrode. Therefore, we are interested in controlling the potential drop across the interface between the surface of the working electrode and the solution (i.e., the interfacial potential). However, it is impossible to control or measure this interfacial potential without placing another electrode in the solution. Thus, two interfa...
متن کاملCyclic voltammetry at micropipet electrodes for the study of ion-transfer kinetics at liquid/liquid interfaces.
Cyclic voltammetry at micropipet electrodes is applied to the kinetic study of ion transfer at liquid/liquid interfaces. Simple and facilitated transfer of an ion that is initially present outside a tapered pipet was simulated by the finite element method, enabling complete analysis of the resulting transient cyclic voltammogram (CV) with a sigmoidal forward wave followed by a peak-shaped rever...

Peptide nucleic acid (PNA), the DNA mimic with electrically neutral pseudopeptide backbone, is intensively used in biotechnologies and particularly in single-base mismatch detection in DNA hybridization sensors. We prop...
متن کاملAdsorptive stripping voltammetry of antibiotics rifamycin SV and rifampicin at renewable pencil electrodes.
Adsorptive stripping voltammetry of antibiotics of rifamycin SV (RSV) and rifampicin (RIF) was investigated by cyclic voltammetry and differential pulse voltammetry using a renewable pencil graphite electrode (PGE). The nature of the oxidation process of RSV and RIF taking place at the PGE was characterized. The results show that the determination of highly sensitive oxidation peak current is t...
