摘要: Abstract An original construction of renewable metallic annular band electrodes (RAgABE and RAuABE) a simple device for fast electrochemical activation the are presented. The most important advantage this hardware is possibility transfer electrode from cell to measurement without any contact with air in conditions securing minimal distortion inflexible part double layer. effectiveness RAgABE was presented solutions highest (200 mg L −1 ) Triton X-100 concentration. analytical applicability confirmed by means quantitative determination nanomolar concentrations Pb(II). RAuABE tested Cu(II) non-pretreated water samples (without removal oxygen surfactants). Excellent repeatability reproducibility – also organic were reached period few weeks, through renovation before each measurement. advanced signal processing procedures applied curves transformation extraction maximum relevant information experimental data.
