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

Ultrafiltration membranes were produced from carboxylated polysulfone polymers having
different degrees of substitution (DS). Solute separation was found to increase with …

A slit sieve model has been used to develop a general correlation between the average
pore size of the upstream surface of a membrane and the molecular weight of the solute …

Three polysulfone asymmetric ultrafiltration membranes having distinctly different
ultrafiltration properties were characterized by high-resolution scanning electron microscopy …

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 …

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 …

The ability of hemodialysis membranes to sieve or reject solutes during ultrafiltration has
been measured for several solutes and three membranes. The membranes tested included …

This paper shows how retention curves of ultrafiltration membranes can be measured with
only one single ultrafiltration experiment by using a dextran solution. This is achieved by …

The characteristic behaviour of the polysulfone (PSF), poly-(N-vinyl-pyrrolidone)(PVP), N-
methyl-2-pyrrolidinone (NMP) ultrafiltration membrane casting solution system was …

Criteria for membrane comparison are presented based on two structural parameters. Using
a transport model that accounts for steric and hydrodynamic effects, an average pore radius …
