AB  - Broad-spectrum antibiotics from the fluoroquinolone family have emerged as 
      prominent water contaminants, among other pharmaceutical pollutants. In the 
      present study, an antibacterial magnetic molecularly imprinted polymer (MMIP) 
      composite was successfully fabricated using carboxy methyl dextrin grafted to 
      poly(aniline-co-meta-phenylenediamine) in the presence of Fe(3)O(4)/CuO 
      nanoparticles and ciprofloxacin antibiotic. The characteristics of obtained 
      materials were investigated using FTIR, XRD, VSM, TGA, EDX, FE-SEM, zeta 
      potential, and BETanalyses. Afterward, the MMIP's antibacterial activity and 
      adsorption effectiveness for removing ciprofloxacin from aqueous solutions were 
      explored. The results of the antibacterial tests showed that MMIP had an 
      antibacterial effect against Escherichia coli, a Gram-negative pathogen (16 mm), 
      and Staphylococcus aureus, a Gram-positive pathogen (22 mm). Adsorption efficacy 
      was evaluated under a variety of experimental conditions, including solution pH, 
      adsorbent dosage, contact time, and initial concentration. The maximum adsorption 
      capacity (Q(max)) of the MMIP for ciprofloxacin was determined to be 1111.1 mg/g 
      using 3 mg of MMIP, with an initial concentration of 400 mg/L of ciprofloxacin at 
      pH 7, within 15 min, and agitated at 25  degrees C, and the experimental adsorption 
      results were well-described by the Freundlich isotherm model. The adsorption 
      kinetic data were well represented by the pseudo-second-order model. 
      Electrostatic interaction, cation exchange, pi-pi interactions, and hydrogen 
      bonding were mostly able to adsorb the majority of the ciprofloxacin onto the 
      MMIP. Adsorption-desorption experiments revealed that the MMIP could be retrieved 
      and reused with no noticeable reduction in adsorption efficacy after three 
      consecutive cycles.
