摘要: The determination of linuron using differential-pulse voltammetry (DPV) and a cathodically pretreated boron-doped diamond electrode is proposed. Cyclic results showed one irreversible oxidation peak for at 1.29 V (vs. Ag/AgCl (3.0 mol L−1 KCl)) in 0.04 Britton–Robinson (BR) buffer solution (pH 2.0). Under optimized DPV conditions, linear analytical curve was obtained the concentration range 0.61–26.0 μmol with detection limit 0.18 L−1. Similar responses (linearity sensitivity) were employing modified platinum nanoparticles. proposed method successfully applied natural water samples recoveries ranging from 90.9% to 104%.
