Özet

A rigid and porous polymeric adsorbent was prepared from monomers 5-(4-methacrylamidophenyl)-10,15,20-triphenylporphyrin (1%), acrylamide (39%), and cross-linking agent ethylene glycol dimethacrylate (60%) using suspension polymerization technique. The adsorption behavior of bovine serum albumin (BSA) on this adsorbent was studied as a function of the initial BSA concentration (0.4-2.5 mg/mL), pH (4.0-8.0), ionic strength, and type of salt in buffered solutions under batch equilibrium conditions. The amounts of adsorbed BSA at equilibrium at pH 4.0 and 7.0 for 1.0 mg/mL initial concentration of BSA were 743 mg BSA and 412 mg BSA per gram of the adsorbent, respectively. The adsorption process was nearly irreversible. (c) 2007 Elsevier Ltd. All rights reserved.
