Adsorption of prometryne and prometon on 6 kinds of soils was measured with the batch equilibration technique.It was found that adsorption isotherms could fit Freundlich equation well.The excess thermodynamic properties of the triazine in liquid chromatography were also studied.The linear relationship between the composition of the mobile phase and triazine's capacity factor was determined.The adsorption in soil showed some relationship with the excess thermodynamic properties.The excess thermodynamic properties might be considered one of the important parameters of pesticide.
