Two methods of membrane characterization are compared. Both methods are based on the
permeation of dilute solutions containing probe solutes through a membrane. The first …

Porous filtration membranes such as microfiltration and ultrafiltration membranes have been
widely applied in various industries. Recently nanofiltration membranes have been …

Data for the transport of different series of solutes (polyethylene glycol, dextrans and
proteins) are measured through asymmetric sulfonated polysulfone ultrafiltration …

The membrane selectivity can be critically affected by the pore size distribution. We
examined the effect of different pore size distributions on the asymptotic membrane sieving …

The effecti® e diffusion coefficients of dextran and polyethylene glycol in track-etched
polycarbonate membranes were measured using membranes with nominal pore sizes of …

An experimental method is described for measuring the permeability of small tubular (hollow
fiber) membranes by means of an unsteady state diffusion experiment. Permeability data …

An investigation has been made of the extent to which useful similarity relations for solute-
membrane transport coefficients can be obtained by dimensional analysis, as based on …

The analysis of solute and solvent transport through capillaries according to sieving and
Poiseuille flow models allows the calculation of retention curves corresponding to a given …

Knowledge of the pore size distribution of a microfiltration or ultrafiltration membrane is
necessary in order to accurately predict membrane performance in any given application …

A dilute aqueous solution of polydisperse neutral dextrans was used to determine the
sieving properties (flux and rejection) of porous polyacrylonitrile membranes. Gel ermeation …
