Oil absorption and oil-water separation effect of nano/micro-fiber membrane

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.
