COMPARATIVE STUDY OF NEUTRAL CARRIERS IN POLYMERIC LITHIUM ION SELECTIVE ELECTRODES.

Article abstract of DOI:10.1021/ac00122a007

New lipophilic diamide compounds have been synthesized and tested as ionophores for lithium in poly(vinyl chloride) (PVC) membrane electrodes, including compounds with pyridine, furan, dioxanonane, and polyether backbones with different lipophilic diamide groups. The new ionophores were compared with previously reported ionophores under similar measurement conditions with the same plasticizer, tris(2-ethylhexyl) phosphate, in all membranes. Fixed interference and matched potential methods were used to determine relative selectivity coefficients for all the electrodes.
