Abstract

Polyamide ultrafiltration membranes were prepared by dissolving nylon 6 fibers in a mixture of hydrochloric acid, ethanol and water, spreading the dope into a thin film and coagulating in a water bath at room temperature. The membranes were characterized in terms of water flux, molecular weight cut-off, fouling, protein stabilization, average pore diameter and ratio of pore to membrane area (Ap/Am). Dextrans were used to estimate the molecular weight cut-off while bovine serum albumin (BSA) was used for studying the effect of protein adsorption on permeation rate. All the prepared membranes had practically the same molecular weight cut-off of approximately 500 kilodaltons.
