%X The catalyst SO42-/TiO2 was obtained by hydrolyzing industrial titanium sulphate,and its photocatalytic performances was examined for the degradation of phenol.Results indicated that the photocatalytic activity of SO42-/TiO2,which calcined at 650 ℃,exhibited the best catalytic activity,with further increasing calcination temperature,the catalytic activity of phoyocatalyst decreased sharply as the SO2-4 volatilized.The optimum technological conditions for photocatalytic degradation of 50 mg/L phenol prefiltration solution were reaction time of 2 h,pH of 7,catalyst dosing quantity of 1 g/L.The catalyst SO42-/TiO2 was characterized by means of XRD,SEM and FTIR,and the results showed that the Ti species in all tested catalysts were in the form of anatase structure,the doped SO42- had a uniform dispersion on TiO2 surface without aggregation in bulk.A preliminary judgement got from FTIR analysis was that the SO42-,adsorbed in the surface of TiO2,calcined at low temperature(<550℃) was the chelating double coordination type,while the bridge type at high calcination temperature(>550℃).
