Abstract: The selective removal of target dye and the reuse of other dye in a dye mixture was achieved by modifying TiO2 with molecularly imprinted polymer (MIP-TiO2). MIP-TiO2 was further immobilized in polysulfone (PSf) ultrafiltration membrane to eliminate the recovery of the particles. MIP-TiO2, enhance the separation capability of PSf membrane and create the selectively photocatalytic property on PSf membrane. MIP-TiO2 achieved an ideal selectivity of methylene blue/methylene orange up to 2.00 within 5 cycles under the irradiation of UV. The selective MIP-TiO2 was blended into PSf membrane before phase inversion. The selectivity of dye removal was further enhanced to 2.83 using the PSf membrane blended with MIP-TiO2 nanoparticles in the integrated photodegradation-ultrafiltration process. The improvement was caused by the surface charge of PSf membrane. On the other hand, the permeability of PSf membrane was enhanced after incorporating MIP-TiO2
