A kinetic equation for the analysis of the degradation reaction of xenobiotic molecules in the soil/water mixture has been derived. By means of this equation we have evaluated the microscopic rate constant for the abiotic hydrolysis of the herbicide diuron in the water phase of a soil/water mixture assuming that the reaction occurs only in the water phase and that diuron is reversibly adsorbed by the soil with a higher rate.

Abstract
A kinetic equation for the analysis of the degradation reaction of xenobiotic molecules in the soil/water mixture has been derived. By means of this equation we have evaluated the microscopic rate constant for the abiotic hydrolysis of the herbicide diuron in the water phase of a soil/water mixture assuming that the reaction occurs only in the water phase and that diuron is reversibly adsorbed by the soil with a higher rate. The soil catalytic capacity on the hydrolysis of diuron was evaluated. © 2003 Elsevier Ltd. All rights reserved.File in questo prodotto:
