Photocatalytic Degradation of C.l.Reactive Red 2 on the Mixture of Ti02 and HZSM.5-Zeolite

摘要：

A mixture of Ti02 and HZSM-5 zeolite was used for photocatalytic degradation of an azo dye，C.I.Reactive Red 2(RR2).The adsorption of RR2 on TiO2 and the effect of Ti02 concentration were studied．HZSM-5 addition was also investigated to ascertain the function of the zeolite on RR2 decoloration．The results show that．The azo dye iS quite stable under exposure Of UV-C light．Less than 1.7％Of the dye was adsorbed on TiO2 surface and 20 min was needed to reach dye adsorption equilibrium．The optimum TiO2 concentration was 320 mg/1.RR2 adsorption rate increased to more than 40％when HZSM-5 addition amount increased to 0.6 g in the solution．The total decoloration rate increased with the addition of HZSM-5 although zeolite addition could not enhance photocatalytic activity of TiO2．
