M. Bochenska et Jf. Biernat, SULFONAMIDES AS IONOPHORES FOR ISE .3. GUANIDINIUM ION-SELECTIVE ELECTRODES BASED ON LIPOPHILIC BIS-SULFONAMIDE PODANDS, Journal of coordination chemistry, 27(1-3), 1992, pp. 145-149
PVC membrane ion-selective electrodes based on bis-sulfonamide podands
and DOS (Bis(2-ethylhexyl)sebacate) as plasticizer are described. The
y were found to behave as guanidinium ion sensors, exhibiting high sel
ectivity for guanidinium ions over potassium ions.
