Catalytic Agent Degradation on Oxide Films and in Microheterogeneous Solution Systems
Abstract
Both photocatalytic and dark decompositions of the organophosphate compounds diethylbenzylphosphonate (DBP) and diethylethylphosphonate (DEP) were investigated in the presence of hydrogen peroxide as oxidant. The role of colloidal TiO2 and ferric sulfate as promoters for the complete mineralisation of the agent was explored. Fundamental studies under the same experimental conditions on the degradation of the aromatic species nitro-o-oxylene (NOX) were likewise undertaken in order to more clearly elucidate the aromatic ring breaking mechanism. The combined effects of dark catalysis and band gap excitation were investigated.
