| Abstract: | Three kinds of surfactants (Acrylic acid,Tween20,S.D.S) were applied to modify the surface of polysulphone hollow fiber membrane.The results indicated that these surfactants could improve hydrophilicity.The regression model was established and the capillary ascending quantity obtained under an optimum working condition.The result counted by a regression equation showed that the modified effect of surface of polysulphone hollow fiber membrane,as a clearing treatment membrane to fruit juice.S.D.S was most effective. |
