Abstract
The herbicides 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) were degraded in acidic aerated solutions of H 2 O 2 and Fe 2+ or Fe 3+ . Conditions leading to complete mineralization could be achieved using Fe 3+ /H 2 O 2 , which thereby became the focus of the study. Herbicide transformation by Fe 3+ /H 2 O 2 , was sensitive to pH (optimum, 2.7-2.8) and was inhibited by methanol or chloride due to scavenging of the active oxidant, and by sulfate due to complexation of Fe 3+
