abstract = "Monitoring heavy metal ion levels in water is essential for human
health and safety. Electroanalytical techniques have presented
important features to detect toxic trace heavy metals in the
environment due to their high sensitivity associated with their
easy operational procedures. Square-wave voltammetry is a powerful
electrochemical technique that may be applied to both
electrokinetic and analytical measurements, and the analysis of
the characteristic parameters of this technique also enables the
mechanism and kinetic evaluation of the electrochemical process
under study. In this work, we present a complete optimized study
on the heavy metal detection using diamond electrodes. It was
analyzed the influence of the morphology characteristics as well
as the doping level on micro/nanocrystalline boron-doped diamond
films by means of square-wave anodic stripping voltammetry (SWASV)
technique. The SWASV parameters were optimized for all films,
considering that their kinetic response is dependent on the
morphology and/or doping level. The films presented reversible
results for the Lead [Pb (II)] system studied. The Pb (II)
analysis was performed in ammonium acetate buffer at pH 4.5,
varying the lead concentration in the range from 1 to 10 ug.L-1.
The analytical responses were obtained for the four electrodes.
However, the best low limit detection and reproducibility was
found for boron doped nanocrystalline diamond electrodes (BDND)
doped with 2000 mg L-1 in B/C ratio.",
