摘要: Boron-doped diamond (BDD) was used as solid electrode material for the simultaneous detection of trace lead and copper in solution using anodic stripping voltammetry (ASV). Peaks due to Cu Pb were identified conditions under which independent measurements each can be undertaken are delineated. Voltammetry AFM imaging is show that while both metals nucleate their pure phases on BDD, once formed nuclei act favorable sites subsequent nucleation growth lead; latter inhibiting hydrogen evolution surface. However conditions, preferentially oxidized, an extra peak at freshly exposed appears SWV experiments. Nevertheless, ASV BDD electrodes provides basis a method via conventional standard addition procedures.
