Abstract:
T iO2 film w as prepared on activa ted carbon fibre by hydro lysis techn ique, using su lphate titan ium as star-t ing m ate ria,l and 254 nm UV-ray as the light sources, and aqueous pheno l so lution of 40m g /L was photoca talytic decomposed ov erT iO2 film, then the rem ova l rate o f pheno l was analyzed. The photodeg rada tion behav ior of T iO2 /ACF and the sorption of ACF w as investigated in aqueous so lution us ing pheno l as a ta rget po llutant. The resu lt show ed tha t the optim a l pho to ca talytic degradation o f phenol w as ach ieved under the condition o f pH = 7~ 8, and percentage o f decom posed pheno l increased w ith increased intensity o fUV- ray. It was found that theT iO2 film exh ibited a deg radation effic iency o f 88.2% for pheno l after 4 h, w ith the cond ition o f pH = 7.5, the concentration of pheno l 40 m g /L, and pow er of u ltrav io le t light 11 75W /L. It w as e ffective to put H2O2 into so lution.
