AB  - Novel magnetic molecularly imprinted polymers (MMIP) were prepared for selective 
      removal of norfloxacin by effectively utilizing photocatalytic degradation and 
      magnetic separation techniques. The imprinted material with titanium layer and 
      multihole surface showed an excellent photocatalytic property. In this paper, the 
      kinetics of photocatalytic degradation of norfloxacin by MMIP was explored, and 
      the influences of environmental factors, including solution pH, humic acid, 
      common ions and water media on photocatalytic performance of MMIP were 
      elucidated. The results showed that MMIP had good adaptability and could degrade 
      norfloxacin within 60 min, but the degradation rate constant decreased in surface 
      water. Based on the identification of intermediate products, the possible 
      degradation pathways of norfloxacin were analysed, speculating that it might be 
      degraded into small molecules in the form of de-piperazine ring, de-carboxyl 
      group and de-fluorine. Moreover, the mineralization ratio of norfloxacin could 
      reach 84.2% after ultraviolet irradiation for 150 min, and the low cobalt release 
      of MMIP enhanced the security of the material. The results of adsorption and 
      degradation cycle tests showed that MMIP obtained by molecular imprinting 
      technology had excellent performance in sustainable use for micro organic 
      pollutants removal.
