中文摘要	a bismuth-film modified graphite nanofibers-nafion glassy carbon electrode (bif/gnfs-na/gce) was constructed for the simultaneous determination of trace cd(ii) and pb(ii). the electrochemical properties and applications of the modified electrode were studied. operational parameters such as deposition potential, deposition time, and bismuth ion concentration were optimized for the purpose of determination of trace metal ions in 0.10 m acetate buffer solution (ph 4.5). under optimal conditions, based on three times the standard deviation of the baseline, the limits of detection were 0.09 mu g l-1 for cd(ii) and 0.02 mu g l-1 for pb(ii) with a 10 min preconcentration. in addition, the bif/gnfs-na/gce displayed good reproducibility and selectivity, making it suitable for the simultaneous determination of cd(ii) and pb(ii) in real sample such as river water and human blood samples.
