摘要：

The transfer of three s-triazine herbicides, atrazine (ATR), propazine (PRO) and prometrine (PROM), across the water/1,2-dichloroethane 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 and peak current as a function of pH. It is shown that the determination of 2.5 x 10(-5) M - 5 x 10(-4) M concentration of herbicides in aqueous phase may be possible under the experimental conditions employed.
