Abstract

The herbicide trifluralin was analysed by adsorptive stripping voltammetry on a glassy carbon electrode. The linear concentration range was 2.5 × 10−7 M – 1.25 × 10−6M when using 5-min preconcentration at open circuit conditions in Britton-Robinson buffer of pH 7.0. The detection limit of trifluralin was 2.5 × 10−8M. The relative standard deviation was 3.3% at a concentration of 1.0 × 10−6M (n=5). The method was applied to the determination of trifluralin in soil with good recovery.
