The aim of this study was to improve the knowledge of interfacial processes of herbicides which appear at natural phase boundaries (soil-soil solution, water-sediment/suspended particles. The adsorption behaviour of diflufenican (DFF), mesosulfuron-methyl (MSM) and iodosulfuron-methyl-sodium (ISMS) (<i>i.e.</i> active substances of the herbicide Alister Grande 190 OD manufactured by Bayer Crop Science) was investigated at the hydrophobic mercury electrode surface using electrochemical method (AC volatammetry). Non-equilibrium adsorption isotherms were discussed. The adsorption strength of the studied herbicides are arranged as follows: MSM &gt; DFF &gt; ISMS. All herbicides belong to less adsorbable substances at the mercury electrode at given experimental conditions. According to our results, they create porous layer on the Hg electrode.<br/>
