摘要：
The herbicide trifluralin was analysed by adsorptive stripping voltammetry on a glassy carbon electrode. The linear concentration range was 2.5 x 10(-7) M - 1.25 x 10(-6)M 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 x 10(-8)M. The relative standard deviation was 3.3 % at a concentration of 1.0 x 10(-6)M (n=5), The method was applied to the determination of trifluralin in soil with good recovery.
