“…Metal Affinity Functionalization of Gel. Gels were immobilized with Cu 2+ ions by incubating in excess 0.05 M copper sulfate solution , at room temperature for 24 h. They were then repeatedly washed with DI water for 3 days to remove all the unchelated Cu 2+ ions. Copper contents in the gels were measured using induction coupled plasma analysis (ICP, Thermolectron IRIS Interpid II) at the USDA Greenhouse Production Research Group at the University of Toledo.…”

A molecular design approach is used to develop thermally responsive metal affinity hydrogels of N-isopropylacrylamide which can retain the nature of the overall volumetric response of the base gels and provide highly specific affinity separation. The synthesis of a novel iminodiacetic acid monomer to obtain metal affinity hydrogels with the right hydrophobic/hydrophilic balance is described and compared to a grafting technique presented in an earlier study. Copolymerization of this monomer with N-isopropylacrylamide and detailed characterization of both materials by various spectroscopic and elemental analysis techniques are presented. Preliminary experiments on the equilibrium swelling and critical analysis of the phase transition of the N-isopropylacrylamide gels incorporated with these novel metal affinity groups indicate that these gels retain the phase transition behavior of the base gels.

“…From the experiments it is observed that Cu 2+ and Cd 2+ are responsive to the IDA-PPy modified CPE. The response of Cd 2+ is limited to 1 × 10 −6 M, while for Cu 2+ the limit is 1 × 10 −7 M. Reports indicate that iminodiacetic acid has a higher stability constant for Cu 2+ than any other divalent metal ion which explains this peculiar behavior [36,37]. However, the other chosen metal ions do not respond in the concentration range of interest.…”

Two new diethyl iminodiacetate-containing monomers (EBMA-ID and CMAC-ID) were synthesized through the reaction of ethyl a-bromomethacrylate (EBMA) and a-chloromethacryloylchloride (CMAC) with diethyl iminodiacetate (ID). The hydrolysis of the ethyl ester groups with potassium hydroxide gave two chelating monomers with potassium salt of iminodiacetic acid (EBMA-IDA-K 1 and CMAC-IDA-K 1 ). The homopolymerization and copolymerization with 2-hydroxyethyl methacrylate (HEMA) of EBMA-ID and CMAC-ID were investigated by photodifferential scanning calorimetry at 408C using 2,2 0 -dimethoxy-2-phenyl-acetophenone (DMPA) as initiator. The monomers showed very low homopolymerization reactivity which may be attributed to the steric effect of N,N-disubstituted methacrylamides, the presence of allyl amine group that can undergo degradative chain transfer and the bulky ID group close to the double bond. Also, addition of these monomers to HEMA decreased polymerization rate and conversion with fraction added. EBMA-IDA-K 1 and CMAC-IDA-K 1 were copolymerized with acrylamide in water using 2,2 0 -azobis(N,N 0 -amidinopropane) dihydrochloride (V-50) initiator. Here also, it was observed that the incorporation of the synthesized monomers into acrylamide reduced both the rate of polymerization and conversion. The copolymers were characterized by 1 H-NMR spectroscopy, thermogravimetric analysis (TGA) and Fourier transform infrared (FTIR) spectroscopy. The UV-visible and TGA spectra confirmed that the synthesized monomers showed chelating ability for Ni 12 and Cr 13 .
