This study reports on the degradation of quinoline and phenol by hydrogen peroxide in the presence of the minerals magnetite and hematite. Our work has focused on clarifying the role of the mineral surfaces and the importance of reactions in solution. Both quinoline and phenol were degraded by hydrogen peroxide in solutions containing the mineral and in equilibrated solutions without mineral. The rate of loss was found to be greater in the presence of magnetite, but the filtered solution still exhibited comparable reactivity. We conclude that surface reactions need not be hypothesized to explain the degradation of the contaminants we studied. It is hypothesized that it is released iron acting as the primary reactant with hydrogen peroxide in solution leading to contaminant degradation. Further work continues to elucidate the role of non reductive and reductive dissolution reactions and organic intermediates in the removal of contaminants.
