Abstrakt

Optimum conditions are described for the determination of micromolar and submicromolar concentrations of herbicides Acifluorphen, Oxyfluorphen and Nitrophen by differential pulse voltammetry (DPV) on non-toxic solid silver amalgam electrode with modified meniscus in Britton-Robinson buffers at different pH. The detection limits are in the range 10-6-10-7 mol L-1. DPV determination of Acifluorphen in BR buffer at pH 2 using a carbon paste electrode was developed with a detection limit of 5•10-7 mol L-1.
