The improving of knowledge about the ion-selective electrodes membrane
configuration and mechanism of potential development rendered the qua
lity of analytical information obtained by ion-selective membrane elec
trodes utilization to increase. Some important ion-selective membrane
electrodes described for the pharmaceutical analyses are presented. Al
so, one of the most recently introduced important class of membrane el
ectrodes, namely, the enantioselective-membrane electrodes class, is p
resented briefly.
