Özet

2-Hydroxyethylmethacrylate (HEMA) based ion-imprinted cryogel membranes (IIP) were synthesized using histidine containing functional monomer, N-methacryloyl-L-histidine (MAH) as complexing/chelating agent, Cu(II) ions as template, methylene bisacrylamide as cross-linker, TEMED and APS as redox pair in both magnetic and non-magnetic forms through free radical polymerization method for selective Cu(II) ion removal. A control non-imprinted cryogel (NIP) was also prepared for comparison. The matrices were characterized by swelling tests, scanning electron microscopy (SEM), BET, and FTIR. Effect of several parameters (pH, temperature, contact time, etc.) on adsorption capacities was examined in batch mode.
