Title

Lead-Selective Neutral Carrier Based Liquid Membrane Electrode

Abstract

Certain synthetic, lipophilic oxa- and dioxadlcarboxylic amides act as lead-selective neutral carriers in liquid-membrane electrodes. Lead Is detected as monovalent permeating species of the type PbX+ (X: OH-, CI-, NO3-, CH3COO). Membranes based on N,N-dioctadecyl-N’,N′-dipropyl-3,6-dloxaoctanedlamide reject alkali metal Ions by a factor of at least 103 and alkaline-earth metal Ions by at least 104. © 1984, American Chemical Society.
