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 meniscus modified solid silver amalgam electrode 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.
