Diesel oil was used as adsorbate, while corn stalk, wheat straw and sawdust were used as natural sorbents for adsorbing and absorbing pure oil and oil in water. The results showed that all three agricultural wastes absorbed diesel. The corresponding saturated sorption amounts of wheat straw, corn stalk and sawdust were 8.54 g g –1 , 7.03 g g –1 and 8.2 g g –1 . The optimum conditions found were: corn stalk particle size between 830 and 1700 μm, oscillation frequency of 0 r min –1 , i.e., no wave movement, oil film thickness of 0.55 mm and adsorbent dosage of 0.29 g; sawdust particle size between 830 and 1700 μm, oscillation frequency of 0 r min –1 , oil film thickness of 0.55 mm and adsorbent dosage of 0.25 g; wheat straw particle size between 500 and 830 μm, oscillation frequency of 0 r min –1 , oil film thickness of 0.55 mm and adsorbent dosage of 0.24 g.
