AB  - In this study, we investigated a highly efficient adsorbent that can be recycled 
      from the soil. Walnut shells were used as raw materials to prepare original 
      ecological biochar (OBC), illite modified biochar (IBC), FeCl(3) modified biochar 
      (magnetic biochar; MBC), and illite and FeCl(3) modified biochar (IMBC), which 
      were tested as low-cost adsorbents. The agents were used to remove metolachlor 
      (MET) from soil. Scanning electron microscopy, Fourier transform infrared 
      spectroscopy, X-ray diffraction, magnetic sensitivity curve analysis, and a 
      series of adsorption experiments were conducted to study the interaction between 
      illite and MBC, and the effect on MET adsorption. Compared with OBC, IMBC had 
      more adsorption sites on the surface. IMBC improved the hole filling effect 
      during the adsorption process. IMBC had more oxygen-containing functional groups 
      and it performed better at removing organic matter through pi-pi interactions. 
      According to the Langmuir model, the Q(0) values for IBC, MBC, and IMBC were 
      91.74 mg g(-1), 107.53 mg g(-1), and 129.87 mg g(-1), respectively, which were 
      significantly higher than that for OBC (72.99 mg g(-1)). The response surface 
      model was used to explore the optimal adsorption conditions for IMBC. After three 
      regeneration cycles, the MET adsorption rate with IMBC was still 81.38% and the 
      MET recovery rate was 98.12%. Therefore, IMBC was characterized as an adsorbent 
      with high efficiency, low cost, and good recyclability. In addition, we propose a 
      suitable agricultural system for recovering MBC on site in the field.
