在常温下通过超声雾化使乙醇和表面活性剂富集。2.4 MHz超声照射产生的液体颗粒直径小于10 μ m，在较低浓度范围内富集率较高，随溶质浓度的增加富集率降低。对于乙醇富集，输入到振荡器的能量远小于分离溶液的潜热。因此，预期这种分离的能量需求比蒸馏小。测量液滴大小分布以表征溶液的雾化行为。阴离子表面活性剂DBS-Na的富集率通过KCl的加入得到了显著提高。结果表明，表面吸附对非挥发性物质的分离具有重要意义。介绍了浓缩日本米酒的实际应用。
Ethanol and surfactants were enriched from the aqueous solutions through ultrasonic atomization at ambient temperature. Liquid particles produced with irradiation of 2.4 MHz ultrasound had diameters less than 10 mu m. High enrichment ratio was obtained at lower concentration range and the ratio decreased with increasing the solute concentration. For ethanol enrichment, energy input to the oscillator was much smaller than the latent heat of the separated solution. Thus it is expected that energy requirement of this separation is smaller than distillation. Drop size distribution was measured to characterize the atomization behaviour of solutions. Enrichment ratio of an anionic surfactant, DBS-Na was remarkably improved by adding KCl to the solution. The result indicated that the significance of surface adsorption to the separation of nonvolatile substances. Production of concentrated Japanese rice wine was presented as a practial application.
