Fourier transform infrared spectroscopy (FTIR) andscanning electron microscope (SEM) were used to characterize the biosorbent before and after adsorption. Batch tests were employed as a functionof the contact time, adsorbent dose, and the pH of the solution. Theexperimental results show that increases the amount adsorbent dosage, pHand contact times, the removal efficiencies were increases and optimumcondition was obtained at pH value equal to 9, 5000 ppm adsorbent dose and45 minutes contact time for removal about 94.5% of crude oil, for test sampleinitial crude oil concentration 257.06 ppm. Therefore, it can be disposed ofwithout environmental damage. The better fitting for equilibrium sorptionprocess data were satisfactorily by the Freundlich isotherm model with (R2=0.9665) and the adsorption kinetics best described by a pseudo-second-orderkinetic model.
