Abstract
AbstractBoron‐doped diamond (BDD) electrodes were used in a single‐compartment electrochemical cell to monitor the degradation of organic matter (OM) and the detection of lead in water. Using sulfuric acid as the electrolyte, the mineralization step was almost complete after 20 min under galvanostatic electrolysis conditions, irrespective of the OM [i. e. phenol or humic acid (HA)]. Nevertheless, H2SO4 was not suitable for samples containing Pb(II), as it induces PbSO4 precipitation. On the other hand, the use of HNO3 resulted in a decrease in the HA degradation yield to 30 %, but remained at 90 % for phenol without any interference with respect to lead detection. Under these latter experimental conditions, the assay of Pb(II) was performed by using differential pulse anodic stripping voltammetry. The BDD electrode exhibited a linear response in the range 1–10 ppm with a normalized sensitivity of 2.66 nC ppm−1 min−1. Accurate results were obtained in solutions containing 20 ppm phenol, as compared to reference technique analysis.
