Removal of cadmium(II) ions from human plasma by thionein modified pHEMA based membranes

摘要

Microporous poly(2-hydroxyethylmethacrylate) [pHEMA] membranes carrying Cibacron Blue F3GA and/or thionein were prepared and used for cadimium(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 umol/cm~2. Then, thionein was adsorbed onto the Cibacron Blue F3GA-carrying membranes. The maximum amount of thionein adsorbed was 0.92 umol/cm~2.
