Abstract

Certain synthetic, lipophilic oxa- and dioxadicarboxylic amides act as lead-selective neutral carriers in liquid-membrane electrodes. Lead is detected as monovalent permeating species of the type PbX** plus (X: OH** minus , Cl** minus , NO//3** minus , CH//3COO** minus ). Membranes based on N,N-dioctadecyl-N prime ,N prime -dipropyl-3,6-dioxaoctanediamide reject alkali metal ions by a factor of at least 10**3 and alkaline-earth metal ions by at least 10**4.
