Abstract
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 (0.4-2.5Â 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 1.0Â mg/mL initial concentration of BSA were 743Â mg BSA and 412Â mg BSA per gram of the adsorbent, respectively. The adsorption process was nearly irreversible.
