AB  - Chlorinated organic and phenolic compounds are still purely studied by many 
      researchers because of their severe damage to the aquatic environment and their 
      carcinogenic effect on many living organisms. Therefore, there is a great 
      interest in removing these environmental pollutants from aqueous mediums by easy 
      and inexpensive methods. Herein, novel nickel ferrite (NiFe(2)O(4)) nano 
      composite modified with poly(aniline-co-o-toluidine) (PAOT) is prepared, 
      characterized, and used for the removal of 2,4-dichlorophenol (2,4-DCP) as an 
      organic chlorinated environmental pollutant. The morphological properties of the 
      composite are characterized by Fourier transform infrared spectrometry (FTIR), 
      X-ray diffraction (XRD), high-resolution transmission electron microscopy 
      (HR-TEM), and Brunauer-Emmett-Teller (BET) methods. The prepared composite is 
      tested for the removal of the hazardous dichlorophenol pollutant from aqueous 
      solutions. Under optimized conditions and with effective control of parameters 
      including, contact time, pH of the test solution, adsorbent dose, and 
      temperature, over 83% of the pollutant is adsorbed and removed. The adsorption 
      capacity is 162 mg g(-1). Adsorption kinetics, adsorption isotherm and some 
      physicochemical parameters of the reaction are evaluated. The Redlich-Peterson 
      isothermal model is the appropriate model for describing the adsorption process. 
      These results indicate that NiFe(2)O(4)/PAOT nanocomposites are promising 
      adsorbents for the removal of persistent organic pollutants (e.g., DCP) from 
      aqueous solutions. The results also reveal that modification of NiFe(2)O(4) 
      particles with poly(aniline-co-o-toluidine) (PAOT) significantly enhances the 
      adsorption capacity of the adsorbent. This is probably due to the electrostatic 
      attraction and non-covalent interactions (e.g. pi-pi) between the aromatic rings in 
      both dichlorophenol and poly(aniline-co-o-toluidine) copolymer. Advantages 
      offered by using NiFe(2)O(4)/PAOT nanocomposites are the high stability, 
      reasonable efficiency, reusability for at least five adsorption-desorption cycles 
      and the ability to remove the adsorbent from aqueous solutions for reuse using an 
      external magnetic field.
