中文摘要：研究利用铅(II)离子为模板、甲基丙烯酸为聚合单体、8-羟基喹啉为配体、二甲基丙烯酸乙二醇酯为交联剂和偶氮二异丁腈为起始剂合成了一种离子印记聚合物。该聚合物可用于制备铅离子选择性电化学传感器吸收和追踪铅(II)离子。这种铅离子-印记聚合物可用于检测食品或水样中痕量铅(II)离子的浓度，标定线性范围为0.05 - 60 mu M，检测限为0.01 mu M。
外文摘要：An ion imprinted polymer (IIP) was synthesized by using Pb(II) as a template, methacrylic acid as a monomer, 8-hydoxyquinoline as a ligand, ethylene glycol dimethacrylate (EGDMA) as a crosslinker, and azobisisobutyronitrile as initiator. It can be applied to prepare lead ion selective voltammetric sensor for Pb(II) adsorption and trace detection. The Pb(II)-IIP was characterized by FTIR spectra and SEM image. Under optimized conditions of polymerization, the Pb(II)-IIP showed good adsorption behavior toward Pb(II), with a magnitude of three times higher than that of the non imprinted polymer (NIP). Also, it exhibited a favorable selectivity for Pb(II), compared with other heavy metal ions of Hg(II), Cd(II), Cu(II), and a negligible adsorption to the other cations. The synthesized IIP was used to determine trace levels of Pb(II) in food and water samples, with a calibration linear range over Pb(II) concentrations of 0.05 - 60 mu M and a limit of detection at 0.01 mu M.
