A PVC membrane with 4-hydroxy salophen as an ionophore along with sodium tetraphenyl
borate (NaTPB) as an anion excluder and dibutyl phthalate as a solvent mediator in the ratio
28.7: 3.3: 63.2: 4.7 (w/w)(PVC–NaTPB–DBP–ionophore) exhibits good properties with a
Nernstian response of 30.1±1.0 mV per decade of activity for Cd (II) ions and a working
concentration range of 1.0× 10− 6–1.0× 10− 1 mol L− 1 Cd (II). The limit of detection was
8.4× 10− 7 mol L− 1 Cd (II). The sensor has a fast response time of 20 s and can be used ...
