             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.",
