摘要：

The degradation of the herbicide imazapyr has been carried out by three advanced oxidation processes involving iron ions as catalysts: Fenton's reagent, photo-Fenton and electro-Fenton. We show that all processes are rapid and efficient. The kinetic rate constant was found to be k=5.4x10(9) M-1 s(-1). The mineralization of imazapyr is almost complete using the photo-Fenton and electro-Fenton processes.
