Heterogeneous and homogeneous Fenton processes using activated carbon for the removal of the herbicide amitrole from water

▶ Homogeneous Fenton activity without activated carbon was lower than heterogeneous one. ▶ Iron leaching with heterogeneous Fenton catalysts was very low. ▶ Highest AMT degradation was with homogeneous FeSO4 in presence of activated carbon. ▶ Activated carbon and FeSO4 showed a synergic effect on hydroxyl generation from H2O2.
