Abstract: Rare earth metal ions had been immobilized on TiO2Hal with conducting polymers by ions imprinting technique. The as-prepared ions imprinting photocatalysts had been characterized by SEM, XRD, FT-IR, UVGvis DRS and ICP-AES. The results demonstrated that there were rare earth metal ions in the photocatalysts. The photocatalytic activity of the ions imprinting photocatalysts was studied by the degradation of tetracycline simulated wastewater under the visible light irradiation. Moreover, a series of synthetic factors were also investigated, the results indicated that it was better to choose o-phenylenediamine as functional monomer, the photocatalytic activity of degradation of tetracycline solution could be improved by adding the rare earth metal ions, Y3+ was the most appropriate ion and the best synthetic concentration of Y3+ was 0.02 g. Under the optimal conditions, the photodegradation rate could reach 78.80%
