摘要

Voltammetric determination of nitrate (NO_3~-) in 0.1 M Na_2SO_4 solution (pH 2.0) at copper modified bismuth bulk (BiB/Cu) electrode was presented in this article. Owing to the unique properties of bismuth bulk electrode, the proposed BiB/Cu electrode can be used for determination of NO_3~- without any deoxygenating pretreatment and shows low detection limit (6μM), wide linear range (13μM to 3mM), high sensitivity (31.8μAmM~(-1)cm~(-2)) and good anti-interference. The practical application of the proposed BiB/Cu electrode has been carried out for determination of NO_3~- in real environmental water samples.
