文摘

Photo catalytic degradation of recalcitrant phenolic polymer was studied. pH and concentration was affected the adsorption of syntan on TiO2 surface. EPR study was conformed that OH is a major radical for syntan degradation. Possible pathway of phenolic degradation is proposed by magnetic resonance study. Electro-oxidation was attempted to achieve complete mineralization.
