摘要：
Ion-selective properties of polymeric plasticized membranes of ion-selective electrodes based on 1,2-bis[2-(2-diphenylphosphorylmethylphenoxy)ethoxy]benzene (L1) and 1,2-bis[2-(2-diphenylphosphorylphenoxy)ethoxy]benzene (L2) toward certain bivalent metal cations has been studied. It has been shown that podand L2 can be used as a sensor component of polymeric plasticized membrane of ion-selective electrode for quantitative determination of Pb2+ ions in aqueous solutions. The structure of complexes [CdI2(μ-L1)]2, [Cd(μ-L1)Br2]2 · C2H5OH, and [Cd(L2)2(H2O)2][Cd2I6] has been studied by X-ray diffraction and IR spectroscopy.
