原始语种摘要: Abstract(#br)A nanocomposite based on multiwalled carbon nanotubes (MWCNT) modified with antimony nanoparticles (SbNPs) was synthesized chemically and has been applied to construct an electrode using carbon paste as substrate (SbNP-MWCNT). The developed electrode was applied for the determination of trace heavy metals Pb 2+ and Cd 2+ by square-wave adsorptive stripping voltammetry. The results were compared with those obtained by related electrode configurations such as Sb-film carbon paste electrode (SbF) and Sb-microsphere-multiwalled carbon nanotube composite carbon paste electrode (Sb microsphere -MWCNT) in model solutions. The analytical signals for Pb 2+ and Cd 2+ decreased in the order I Sb-nanoparticle > I Sb-film >...
