Abstract

Three kinds of diamines, i.e., ethylene diamine (EDA), diethylene diamine (DEDA), and triethylene diamine (TEDA), were immobilized to the poly(glycidyl methacrylate) chain grafted onto a porous hollow–fiber membrane. The resultant anion–exchange porous hollow fibers were evaluated as ion–exchangers for protein binding in a permeation mode. The DEDA– and TEDA–immobilized porous hollow fibers exhibited higher flux for a buffer (pH 8.0) and lower binding capacity for bovine serum albumin than the EDA–immobilized porous hollow fiber. This will be due to that DEDA and TEDA crosslink between neighboring epoxy groups of the graft chain.
