이구유개공결구적 ZSM-5비석분자사부재납미 TiO 2제비출성능량호적복합형최화재료．결합소묘전경(SEM)、N2흡부-탈부등온선(BET/BJH 모형)화 X 사선연사진행표정,병장기협동과류산염광최화강해초기분분폐수．결과표명：재 pH 위4．5,최화제투가량위0．8 g/L,,FeSO 4위0．8 g/L,Na2 S2 O 8위1．6 g/L,상온하반응240 min,대초기분분(50 mg/L)거제솔체도98．4％．
The composite catalyst was prepared by nano TiO 2/mesoporous ZSM-5 molecular sieve,scan-ning electron microscope (SEM),N2 adsorption desorption isotherms (BET/BJH model)and X-ray dif-fraction were used to characterize,and the collaborative effect with persulfate for photocatalytic degrada-tion pNP wastewater were investigated.The results show that the pNP(50 mg/L)percent removal of 96. 6% achieved under the catalyst dosage of 0.7 g/L,pH of 4.5,FeSO 4 of 0.8 g/L,Na2 S2 O 8 of 1.6 g/L and reaction time of 240 min at room temperature.The change of the organic contaminants in waste water af-ter treatment were detected by UV-Vis.
