working electrode
[ˈwɜːrkɪŋ ɪˈlɛktrəd]
nounpl: working electrodes
eletrodo de trabalho
1. The electrode in an electrochemical cell at which the reaction of interest occurs; the electrode where oxidation or reduction takes place during electrochemical analysis
In cyclic voltammetry, the working electrode is where the potential is swept and the current response is measured.
Na voltametria cíclica, o eletrodo de trabalho é onde o potencial é varrido e a resposta de corrente é medida.
2. In electroanalytical chemistry, the electrode whose potential is controlled and at which the analytical measurement is performed
The working electrode material must be chemically inert to avoid interference with the experiment.
O material do eletrodo de trabalho deve ser quimicamente inerte para evitar interferência no experimento.
This is a technical term primarily used in scientific and academic contexts, particularly in electrochemistry, analytical chemistry, and materials science. It is essential terminology for researchers and students working with electrochemical instruments and analysis. The term is equally used in both Brazilian Portuguese and European Portuguese scientific communities, though with minor spelling variations.
