Sonovoltammetric determination of 4-nitrophenol on diamond electrodes
| Resumo: | The sonovoltammetric determination of 4-nitrophenol was studied on a boron-doped diamond electrode. Significant improvements in the analytical sensibility were observed due to electrode surface cleaning and the enhancement in the transport of species to the electrode surface provided by ultrasound. Thus, for the oxidation and reduction process, the limit of detection diminished from 11.7 to 3.87 and from 6.38 to 2.57 µg L-1, respectively. |
