Using tetrabutyl titanate and ethanol as reaction raw materials, the photocatalyst of TiO2-coated natural zeolite was prepared by sol-gel method. The experimental techniques of XRD and SEM were used to characterize the prepared TiO2-coated photocatalyst. The experimental results showed that the removal rate of COD from papermaking wastewater can reach 82% at the conditions of pH value 4.0, radiation time 8.0h, amount of catalyst 50g/L. The photocatalyst had a high activity after reused four times. Kinetics ...
