    Preparation and Characterization of Nicotine-Selective Hydrogels
    (Wiley, 2016) Isikver, Yasemin; Ecevit, Tugba
    In this study, P(NIPAAm-MAm)/A, which is a new smart polymer on which the temperature sensitivity of N-isopropyl acrylamide monomer and pH sensitivities of methacrylic acid (MA) and itaconic acid (IA) monomers unite, were prepared by free radical polymerization. The influence of crosslinkers on the properties of polymer and adsorption was studied using two different crosslinkers. These new environmentally multistimuli responsive hydrogels were characterized by FTIR, TG, and DSC. In order to determine the swelling behaviors of polymers, the equilibrium swelling studies were carried out at different temperatures and pHs. With the aim of studying the usability of the prepared polymers in the adsorption of nicotine and its pharmaceutical derivatives, the effects of temperature, pH, and adsorbent mass on adsorption equilibrium were studied.
