Abstract 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 6.7×10 −7 to 2.0×10 −5 mol L −1 , with a limit of detection ( LOD ) of 1.4×10 −7 mol L −1 . The proposed electrode was applied for atrazine determination with satisfactory results compared with a high‐performance liquid chromatography method (HPLC).
