摘要：

In this paper the main techniques (microscopy observations, molecular weight cut-off determinations, porosity measurements) for characterizing ultrafiltration membranes are critically reviewed and discussed. Particular attention is devoted to the problem of evaluating the porosity of the membrane skin layer. Porosity results obtained by testing some commercial ultrafiltration membranes with an automatic instrument based on the combined bubble pressure and solvent permeability method are reported. © 1990.
