AB  - The present investigation deals with the adsorptive removal of crude petroleum 
      oil from the water surface using coconut oil-modified pinewood biochar. Biochar 
      generated at higher pyrolysis temperature (700  degrees C) revealed higher fatty 
      acid-binding efficiency responsible for the excellent hydrophobicity of the 
      biochar. Fatty acids composition attached to the biochar produced at 700  degrees C was 
      (mg g(-1) BC) lauric acid (9.024), myristic acid (5.065), palmitic acid (2.769), 
      capric acid (1.639), oleic acid (1.362), stearic acid (1.114), and linoleic acid 
      (0.130). Simulation of the experimental adsorption data of pristine and modified 
      pinewood biochar generated at 700  degrees C offered the best fit to pseudo-first-order 
      kinetics (R(2) > 0.97) and Langmuir isotherm model (R(2) > 0.99) based on the 
      highest regression coefficients. Consequently, the adsorption process was mainly 
      driven by surface hydrophobic interactions including pi-pi electron-donor-acceptor 
      between electron-rich (pi-donor) polycyclic aromatic hydrocarbons from the crude 
      oil and biochar (pi-acceptor). A maximum adsorption capacity (Q(max)) of 5.315 g 
      g(-1) was achieved by modified floating biochar within 60 min. Whereas the 
      reusability testing revealed 49.39% and 51.40% was the adsorption efficiency of 
      pristine and modified biochar at the fifth adsorption-desorption cycle.
