摘要：

A new method using differential pulse adsorptive stripping voltammetry for the determination of atrazine (ATZ) in natural water samples using a bismuth film electrode (BiFE) is proposed. The calibration curve was linear in the atrazine concentration range from 6.7 x 10(-7) to 2.0 x 10(-5) mol L-1, with a limit of detection (LOD) of 1.4 x 10(-7) mol L-1. The proposed electrode was applied for atrazine determination with satisfactory results compared with a high-performance liquid chromatography method (HPLC).
