摘　　要：Metolachlor retention on a Sharkey clay soil was quantified using a kinetic batch method for different initial solution concentrations. Time-dependent adsorption was carried out by monitoring solution concentration at different reaction times. Adsorption was found to be highly kinetic in nature. Attempts were made to describe metolachlor retention based on a kinetic multireaction model which includes reversible and irreversible retention processes of the equilibrium and kinetic types. The predictive capability of the model for the description of experimental results for metolachlor retention was examined and proved to be adequate.Metolachlor retention on a Sharkey clay soil was quantified using a kinetic batch method for different initial solution concentrations.
