Enhanced controllable degradation ability of magnetic imprinted photocatalyst via photoinduced surface imprinted technique for ciprofloxacin selectively degradation.

The magnetic controllable imprinted photocatalyst fabricated by photoinduced surface imprinted technique exhibits good controllable and selective degradation ability. • MCIP with good recyclability is obtained by photoinduced surface imprinted technique. • MCIP has good controllable degradation ability due to the existence of PNIPAM. • MCIP exhibits good selectivity to ciprofloxacin due to the existence of imprinted cavity. In this article, magnetic controllable imprinted photocatalyst (MCIP) was fabricated by photoinduced surface imprinted technique. The degradation rate of ciprofloxacin by MCIP at 20 °C (70.85 %) was higher than that at 40 °C (55.06 %), compared with other materials, MCIP exhibited good controllable degradation ability due to the state of expansion or contraction at different temperatures. Moreover, when the temperature was 20 °C (or 40 °C), the coefficient of selectivity of MCIP to magnetic controllable non-imprinted photocatalyst (MCNIP) was 2.40 (or 2.80) in the single solution, and the coefficient of competitiveness of MCIP to MCNIP was 1.40 (or 1.37) in the mixed solution, above results indicated that MCIP exhibited good selective degradation ability. This work made the functional application of photocatalyst have a better prospect. [ABSTRACT FROM AUTHOR]
