he transfer of three s-triazine herbicides, atrazine, propazine and prometrine, across the water/1,2-dichlroethane interface was investigated using cyclic voltammetry. A facilitated proton transfer mechanism from the aqueous to organic phase is demonstrated by the analysis of positive peak potential an peak current as a function of pH. It is shown that the determination of 2.5x10-5 M - 5x10-4 Mconcentration of herbicides in aqueous phase may be possible under the experimental conditions employed.
