Adsorption and correlation with their thermodynamic properties of triazine herbicides on soils

Adsorption of atrazine, prometryne and prometon was determined on six soils with different physical and chemical properties. Theadsorption isotherms of three herbicides could well fit Freundlich equation. On all of six soils, adsorption of herbicides increased in the order:atrazine ≈ prometon < prometryne. This order is quite the same to the calculation result of by means of excess thermodynamic properties oftriazine. The Freundlich adsorption constants, Kf, showed to have good correlation with organic matter(OM%) of soils for each of theseherbicides, suggesting that OM is the main factor, which dominates in the adsorption process of these triazine herbicides.
