논문 초록 (Abstract)
Soybean oil was used as a biodegradable extracting agent for the removal of sorbed phenanthrene (PHE) in sandy soil. In this stud y, several methods of forming emulsions using soybean oil and their extraction properties were investigated. The stable and homogene ous oil emulsions were formed more effectively by ultrasonication (U1) t han by homogenization (H1). Moreover, homogenization before ultrasonica tion (HU1) established more stable emulsions than U1 alone. The mean diameter of oil droplets in U1 or HU1 was reduced to the nanome ter range (approximately 70 nm) by U1 with 750 W using a high-power sonic tip operated at 33% amplitude and 20 kHz frequency for 5 min. T he extraction efficiency of sorbed PHE from soil by oil emulsions increased with decreasing size of droplets of oil emulsions; t he maximum extraction of PHE was achieved with HU1. Thus, nano-em ulsions of vegetable oil made by U1 could be an environmentally benign alternative for effectively washing soil.
