Photo-catalytic degradation of phenol with TiO2/Fe3+ coated on glass fiber
|
Abstract:
TiO2/Fe3+/glass fiber was prepared with TiO2 and Fe3+ coated on glass fiber,and Fe3+ was doped as a modification ion.The photocatalytic activity of TiO2/Fe3+/glass fiber was evaluated using phenol as a model substrate.The experimental results demonstrated that TiO2/Fe3+ coated on glass fiber had good degradeation capacity.The optimum conditions evaluated by degradation and mineralization rates of phenol were as follows: wastewater pH of 3~5,O2 of 1.0 L/(min·L),rising velocity of 0.7 m/min,and power of 365 UV high-presser mercury lamp was 250 W.Under the optimum conditions,phenol degradation and mineralization rates could reach 85% and 80%,respectively when initial phenol concentration was 30 mg/L and reaction time lasted 120 min.
