The adsorption of four s-triazines on the A1-horizon of a brown soil from Sardinia was studied. The adsorption isotherms showed to be essentially linear. Prometryne, hydroxipropazine and prometone were highly absorbed at pH 5, scarcely at pH 2. Propazina behaved differently, showing the highest adsorption at low pH values. Adsorption was affected by the acidity of aqueous systems and tends to increase with a decrease in pH, reaching a maximum in the vicinity of the pK of the respective compounds.

Abstract
The adsorption of four s-triazines on the A1-horizon of a brown soil from Sardinia was studied. The adsorption isotherms showed to be essentially linear. Prometryne, hydroxipropazine and prometone were highly absorbed at pH 5, scarcely at pH 2. Propazina behaved differently, showing the highest adsorption at low pH values. Adsorption was affected by the acidity of aqueous systems and tends to increase with a decrease in pH, reaching a maximum in the vicinity of the pK of the respective compounds.| File | Dimensione | Formato | |
