Title: Lariat ethers in silver-selective polymeric membrane electrodes
Author: Liu, Yi
Abstract: There have been many studies of crown compounds as neutral carriers of ion -selective electrodes . The investigations of these complexing agents have focused mainly upon obtaining high affinity and selectivity for given metal ions . When considering the coordination features of heavy metal cations such as Ag+ , it is known that soft donor atoms in the host lonophores are more effective than just hard atom donors based on the hard -soft acid and base (HSAB ) concept . One aspect of this thesis is to investigate the influence of nonionizable side arm which contain soft atom donor sites in sym -dibenzo - 16 -crown lariat ethers upon their complexation and selectivities for silver ion versus alkali , alkaline -earth , transition , and heavy metal cations in solvent polymeric membrane electrodes . The second goal of this thesis is to obtain highly efficient Ag+ selective lonophores .
