摘　　要：油水污物是影响环境清洁性的重要因素之一,为此,分析了纳/微米纤维膜对大豆油、液体石蜡和白油3类油的吸油性和油水分离效果,并与市场用针织超细纤维洁净布、非织造超净无尘布进行比较,综合评价其去油污效果。结果表明,纳/微米纤维膜的吸油性和油水分离效果明显好于2种市场用洁净布,纳米级纤维膜对大豆油、液体石蜡、白油的饱和吸油率分别高达15.1、14.9、15.0 g/g,对油水乳液中油的去除率接近50%,其次是微米级纤维膜,针织超细纤维洁净布的效果最差。Oil and water contamination is one of the important factors that affect the environment cleaniness. This article investigated the oil absorption and oil-water separation effect of nano/micro-fiber membrane to soybean oil, liquid paraffin, and white oil and compared it with commonly-used knitted superfine-fiber clean cloth and nonwoven super clean dust-free cloth in terms of oily soil removal efficiency. It was found that the oil absorption and oil-water separation effect of the nano-fiber membrane is much better than those of the two kinds of clean cloth, and its saturated absorption rate of soybean oil, liquid paraffin, white oil is up to 15.1, 14.9 and 15.0 g/g, respectively, and the oil removal rate from oil/water emulsion is near to 50%. And as far as comprehensive effect is concerned, nano-fiber membrane ranks the first, micro-fiber membrane occupies the second place, and knitted micro-fiber cloth takes the last one.
