  • A hollow fiber membrane containing BSA as ligand was Prepared by radiation-induced grafting GMA onto a porous polyethylene hollow fiber and subsequent reacting with DEA and TEA. The density of the DEA and TEA of the membrane were 3.4 mmol/g, 1.7r mmol/g, respectively. The DEA membrane exhibited a higher amount of than the TEA membrane. BSA was immobilized by the graft chains during the permeation of BSA solution throught the DEA and TEA membrane. The BSA was adsorbed in multilayer binding of 8 onto the DEA membrane whereas adsorption onto the TEA membrane remained constant. A two-stage stepwise BTC was observed due to independent chiral recognition for L, D-Trp solution by DEA-BSA membrane.
