The effect of organic solvent on permeability of hollow fiber membranes modified by interphase polycondensation method
Abstract
The influence of organic solvent properties on polyamide composite hollow fiber ultrafiltration membrane separation performance was studied. It was found that membrane permeability strongly correlates with the surface tension of the solvent: the pure water flux is decreased and rejection increased. The correlation between other physical properties of organic solvent (boiling point, dielectric constant, density, refractive index, etc) and the membrane permeability was not found.
