Researchers performed a controlled reaction on the surface of polyacrylonitrile hollow fibers to change the CN unit to a CNH(2) unit. Ion exchange measurements and infrared spectra suggested the existence of an HN(2) unit on the modified surfaces. The modified fibers possessed a smaller molecular weight cut-off than did the unmodified fibers. Researchers also used the succinimide reaction to immobilize serum albumin on the surface of the modified and unmodified fibers. Ultrafiltration experiments for optical resolution of racemic amino acids were performed using the immobilized albumin membranes. Results showed an extremely effective binding of L-phenylalanine on BSA in the immobilized BSA membranes. The immobilized albumin membranes prepared from the chemically modified hollow fibers demonstrated optical resolution of racemic phenylalanine. Abstract.
