Determinação voltamétrica de 4-clorofenol sobre o eletrodo de diamante dopado com boro utilizando a voltametria de onda quadrada

Abstract: Recebido em 6/1/03; aceito em 6/5/03 ELECTROANALYTICAL DETERMINATION OF 4-CHLOROPHENOL BY SQUARE WAVE VOLTAMMETRY ON BORON-DOPED DIAMOND ELECTRODES. The anodic voltammetric behavior of 4-chlorophenol (4-CF) in aqueous solution has been studied on a Boron-doped diamond electrode using square wave voltammetry (SWV). After optimization of the experimental conditions, 4-CF was analyzed in pure and natural waters using a Britton-Robinson buffer with pH = 6.0 as the supporting electrolyte. Oxidation occurs at 0.80 V… Show more

“…In order to describe these results these authors developed a comprehensive kinetic model that allowed them to predict the trend of the COD and current efficiency for the electrochemical combustion of the organic with BDD electrodes and to estimate the energy consumption during the process. 76,77,110 Other applications of BDD for the destruction and/or determination of organic pollutants were obtained by Avaca and co-workers 105,[131][132][133][134][135][136][137][138][139] where the comparison between the BDD and other anodic materials have permitted use of alternative techniques during the oxidation of the organic pollutants. The BDD electrode is the best choice for several electroanalysis studies, as demonstrated by the electrochemical oxidation of 4-nitrophenol in 0.1 mol L -1 BR buffer electrolyte.…”

“…In most instances this method presents further advantages: no need for sample pretreatment and less sensitivity to matrix effects than other analytical techniques. [22][23][24][25] Natural diamond is an insulator, but when doped with boron this material presents either semiconducting or semimetallic electronic properties, depending on the doping level. Recently, thin films of boron-doped diamond (BDD) emerged as a unique electrode material for several electrochemical applications, especially in electroanalysis.…”
