✦ Synopsis
Electrode membranes were prepared which contained only PVC and a plasticizer. The plasticizers studied were tris( 2_ethylhexyl)phosphate, 2nitrophenyl octyl ether and bis(l-butylpentyl)adipate.
The response and selectivity of these ligand-free PVC electrodes towards alkali and alkaline earth cations are reported.
