dc.description.abstractMicroporous poly(2-hydroxyethylmethacrylate) [pHEMA] membranes carrying Cibacron Blue F3GA and/or thionein were prepared and used for cadmium(II) removal from human plasma. pHEMA membranes were produced by a photopolymerization of HEMA in the presence of azobisisobutyronitrile. The reactive dye-ligand Cibacron Blue F3GA was then covalently attached onto the pHEMA membranes. The maximum dye-loading was 1.07 mu mol/cm(2). Then, thionein was adsorbed onto the Cibacron Blue F3GA-carrying membranes. The maximum amount of thionein adsorbed was 0.92 mu mol/cm(2). The aqueous swelling properties and contact angle lair underwater) of the pHEMA membrane were not observed to change following derivatisation with Cibacron Blue F3GA. These hydrophilic membranes (contact angle value: 45.3 degrees) with a swelling ratio of 58% (w/w), and carrying Cibacron Blue F3GA and/or thionein were used in the Cd(II) removal studies. The maximum amounts of Cd(II) removed from human plasma by Cibacron Blue F3GA-attached and Cibacron Blue F3GA-attached/thionein adsorbed pHEMA membranes were of 1.72 mu mol used as pectively. Cd(II) ions could be repeatedly adsorbed and desorbed with both types of these novel metallo-peptide affinity pHEMA membranes without noticeable loss in their Cd(II) adsorption capacity.
