Notes:
A set of macrocyclic oxamides intended to be used as potential ionophores for lead ions in solvent polymeric membrane electrodes was investigated. The influence of the structure of ligands (number and distribution of oxygen donor atoms and ring size) on the selectivity was examined. Pronounced preference of lead over other divalent and some monovalent cations was observed for the 21-membered-ring oxadiamides (ionophores 1 and 7). These electrodes exhibited a linear response within the activity range of 10-5.4 -10-15 M in Pb(NO3)2 solutions.
