✦ Synopsis

Ionic

mobilities have been measured for K* , Na+, BP&in plasticized PVC membranes, on the assumption that the mobility of AsPht is identical with that of BPG The measurements show that in a typical membrane used as an ISE and containing lo-* M valinomycin + lo-" M KBPh, the transport number of K+val is 0.87 whilst that of BP& is 0.13.

A number of situations which give rise to time dependent impedances have been explored experimentally for plasticized PVC membranesincontact with aqueous solutions. Most ofthe measurements can be explained by assuming that there is loss (or in some cases gain) of ions from the membranes to the conta
