AB  - Diclofenac (DCF) is a pharmaceutical contaminant of water bodies and therefore, 
      improvement of analytical techniques for its removal and quantitation is one of 
      the current interests of analysts. Herein, DCF selective magnetic molecularly 
      imprinted polymer (MMIP) has been fabricated and characterized by Fourier 
      transform-infrared spectroscopy, thermogravimetric analysis, vibrating scanning 
      magnetometer, scanning electron microscopy, high-resolution transmission electron 
      microscope, energy-dispersive X-ray spectroscopy, and Brunauer-Emmett-Teller 
      analyzer. Furthermore, the protocol for the quantification of DCF using 
      MMIP-HPLC-PDA combo has been optimized by investigating the effect of the amount 
      of MMIP, type and volume of eluent, and variation of pH. The optimized protocol 
      suggested a method detection limit of 0.042 ng mL(-1) and linearity of results in 
      the range 0.1-100 ng mL(-1) (R(2) = 0.99). The fabricated material offered 
      recovery of DCF up to 96.38-99.46% from groundwater and pharmaceutical samples 
      with a relative standard deviation of <4%. In addition, the material was found 
      selective and sensitive for DCF among its analogous drugs like mefenamic acid, 
      ketoprofen, fenofibrate, aspirin, ibuprofen, and naproxen.
