Notes:
Cotton, a lignocellulosic fiber and environment friendly natural material, was tested for itsability to sorb diesel oil from the pure diesel oil bath and the diesel oil containing water bath. Thefiber was ground to disrupt the lumen structure or extracted with diethyl ether to remove wax fromcotton. Diethyl ether is an organic solvent and extracts only extractives in the cell wall. Oil sorptioncapacity was the highest in control as 30.6 g/g in the pure diesel oil bath, and the lowest in groundcotton as 0.8 g/g in the diesel oil containing water bath. Cotton is mainly composed of hydrophiliccomponents and sorb water more easily than oil. As a result diesel oil sorption capacity was muchhigher in the oil bath than in the water bath. However, after grinding and passing through 20 meshscreen (0.86 cm), wax is preserved but the lumen structure of cotton, of which the fiber length is about18 mm, is disrupted by grinding and can not hold oil. Therefore, the diesel oil sorption capacity ofcotton was decreased significantly to 5.2 g/g in the pure diesel oil bath, and to 0.8 g/g in the waterbath, compared to those of control. And because wax is removed but lumen structure is not destroyedafter diethyl ether extraction, the diesel oil sorption capacity decreased slightly to 27.7 g/g in the oilbath and to 7.5 g/g in the water. When cotton was presoaked in water, cotton sank during thepresoaking process, and so the oil sorption capacity could not be determined. Grinding, extractingandpresoaking all contributed to the changes in oil sorption capacity. The most significant change isattributed to the reduction in the particle size of cotton
