AB  - Water pollution by oil is a serious environmental problem. Developing new 
      generation of benign adsorbents satisfying several criteria required for real 
      practical application is of great need. This work introduces an effort in this 
      direction, by utilizing a facile synthesis of wood sawdust coated magnetite 
      nanoparticles functionalized stearic acid (WSD@Fe(3)O(4)NPs/SA) as a novel nano 
      composite along with its precursor WSD@Fe(3)O(4)NPs. SA was covalently bonded to 
      the precursor by amide bond formation via the interaction with the silylating 
      agent 3-aminopropyltrimethoxysilane (3-APTS). This mode of binding is more 
      stronger than the conventional ester bond. Fourier transform infrared (FT-IR), X- 
      ray powder diffraction (XRD), Scanning electron microscope (SEM) and 
      Transmittance electron microscope (TEM) were employed for characterization and 
      follow up the synthesis process. Application of the newly synthesized magnetic 
      nano composite adsorbent under optimized parameters of contact time (min) and 
      composite dosage (g) reveal high removal capacity values (g/g) evaluated to be 
      28.32 g/g, 5 min and 0.1 g for used motor oil removal and 41.22 g/g, 10 min and 
      0.1 g for crude oil. The high removal efficiency exhibited by WSD@Fe(3)O(4)NPs/SA 
      was mainly argued to the long hydrocarbon chain of SA moiety and additional ـــ 
      (CH(2))(3) ـــ groups incorporated 3-ATPS. Moreover, Analysis of the oil 
      adsorption experimental equilibrium data were well fitted with Freundlish model 
      with correlation coefficients r(2) = 0.9788 and 0.9896 for used motor oil and 
      crude oil, respectively. The kinetic data were correlated using two kinetic 
      models and the results were in harmony with pseudo-second order.
