- Polysulfone ultrafiltration membranes were modified with dextran, dextran sulfate and diethylaminoethyl (DEAE) dextran. The behavior of the modified membranes towards static adsorption of bovine serum albumin (BSA) was investigated in the pH range 3-7. The modified membranes showed lower flux losses after protein adsorption than unmodified membranes. The plain dextran was considered to be the best choice of the three as a modifying agent. Streaming potentials were measured for DEAE dextran and dextran T500 modified membranes as a function of pH. The isoelectric points of the membranes were 5.9 and 4.6, respectively. Titration data for DEAE and dextran T500 are also presented. The modification of membranes with dextrans of different molecular weight average indicated that the shorter dextran molecules (Dextran T10) gave a better result than the larger ones (Dextran T500).
