Abstract

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