Preparation of TiO2-ZSM-5 zeolite for photodegradation of EDTA

Doping of TiO2 into ZSM-5 zeolite has been achieved by impregnation and solid-solid interaction methods. The incorporation of titanium into framework of ZSM-5 using impregnation method is higher than that of solid-solid interaction method. The photodegradation of EDTA by impregnation method is much better than that of solid-solid interaction method.
