Abstract

The purpose of this study was to examine the various factors that control the kinetics of diuron degradation in irradiated, aerated suspensions containing goethite (α-FeOOH) and oxalate, in the following denoted as heterogeneous photo-Fenton systems. In these systems, attack by hydroxyl radicals (HO) was the only pathway of diuron degradation. Studies were conducted in systems containing initially 80 or 200 mg L-1 goethite (corresponding to 0.9 ...
