Abstract: Adsorption of abametin in 5 different soils was studied by batch equilibration technique. The result showed that soils had strong adsorption of abamectin, which, however, varied with the different properties of the soil tested. The isotherm data were fitted to Fruendlich equation, The Kaf values increased with increasing organic matter and clay content of soil, the correlative coefficient of Kaf values and organic matter and clay content of soil were significantly positive .The free energy of sorption ranged from 10.9859 kJ/mol to 25.1538 KJ/mol indicates that the spontaneity of the given sorption process of abamectin in soils.

Key words: abamectin, soil, adsorption, HPLC
