Fe3+, as a template, was initially complexed with N-methacryloyl-(l)-cysteine methyl ester (MAC) to form MAC−Fe3+ (the complex monomer), which was then polymerized with hydroxyethyl methacrylate (HEMA) to constitude a Fe3+-imprinted poly(HEMA−MAC) monolith (PHEMAC−Fe3+) by bulk polymerization method. The template (Fe3+) was removed from the polymer by 0.1 M EDTA solution. The specific surface area of PHEMAC−Fe3+ was found to be 35.2 m2/g with a swelling ratio of 60.2%. A maximum adsorption capacity of 150 μg Fe3+/g was observed with PHEMAC−Fe3+. It was determined that PHEMAC−Fe3+ possesses relative selectivity coefficients for Fe3+/Cd2+ and Fe3+/Ni2+, which are 42.6 and 36.1, respectively, times greater than nonimprinted monolith (produced in the absence of Fe3+, PHEMAC). The PHEMAC−Fe3+ monolith has been recovered and reused many times without a significant decrease in its adsorption capacity.
