Characterization of ultrafiltration membranes.

Journal of Membrane Science, 1983
Abstract A theory was developed to point out the important parameters involved in the deformation of a flexible polymer in ultrafiltration through membranes. It appears that the deformation, and thus the easier transport of the polymer solute, occurs when the permeate flux reaches (or exceeds) a critical value which depends on the solution ...

Alginate ultrafiltration membranes

Biotechnology Letters, 1985
A simple method of producing ultrafiltration membranes, using calcium and barium alginates, has been developed. Although restricted in their flux and rejection characteristics these membranes offer a cheap model system for studying the fouling of hydrophilic membrane surfaces.

Permeability of ultrafiltration membranes

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1973
1. A study was made of the permeability of a number of ultrafiltration membranes based on cellulose acetate relative to biologically active compounds of variable molecular weight as a function of the composition, solution concentration and the pressure.

Nanoprecipitation for ultrafiltration membranes

Journal of Polymer Science Part B: Polymer Physics, 2015
Polymer nanoparticles are readily obtainable by rapidly mixing a dilute polymer solution and a poor solvent. The nanoparticles of poly(vinylphenol), poly(vinylidene fluoride), and emeraldine base polyaniline prepared by nanoprecipitation become sticky when their diameters decrease down to a few tens of nanometers, and such polymer nanoparticles ...
